I had one of the most extreme play sessions that I've ever had in terms of mob kills - 767 - the second-highest on record, behind 796 in TMCWv4 and ahead of 748 in World1:
On the day before that I was mobbed by a horde of as many as 50 zombies which had spawned from a dungeon, which spawn a pack of 6 mobs every 5-10 seconds so they can quickly accumulate when the dungeon is nearby but not obvious; I went from level 33 to 36 after killing all of them (about 270 XP or 54 mobs without equipment) - just the ones shown in the screenshots, with more elsewhere. One of the zombies also had full iron armor, although I wouldn't classify that as that very rare (I see one every few days; for comparison, diamond armor is about 32 times rarer):
I also found a double cave spider spawner, with the spawners only a few blocks apart; I found a total of 6 spawners within a small area of a single mineshaft (many times I destroy the spawners before I notice more nearby, even when they are in the same corridor, so I don't get many screenshots of multiple spawners):
I've also found several more large caves as well as a bizarre ravine which looped around on itself multiple times, the most unusual ravine that I've seen (at first I thought there were 2-3 ravines but it turned out to be just one, which was also quite long):
This is a complex intersection of multiple caves and a ravine:
This cave was quite long, extending over 100 blocks in length:
Another large cave:
How many ravines do you see? Just one, which intersects itself multiple times:
Also, I've now mined over 400,000 ore, including nearly 100,000 iron:
Notably, since my last update I mined an average of 3299 ore, killed 432 mobs, and gained 6078 XP per play session (for comparison, I averaged 3143 ore, 351 mobs, and 5308 XP per session over 121 sessions spent caving in TMCWv4, the one world which was fully documented in this regard):
(these numbers are total resoruces, total ore, coal, iron, gold, redstone, lapis, diamond, emerald, rails, cobwebs, moss stone, spawners, mobs, XP; I have close to 3 months of these recordings now, which are printed out by the client when I quit the game, and I've thought of making graphs of the data)
I've found quite a few interesting things since my last update, including an absolutely enormous cave which was easily twice the volume of any cave I've found so far, as well as numerous other large caves, and the largest abandoned mineshaft that I've ever found, which also resulted in 154 cave spiders killed in one play session, the most that I can ever recall.
First, I explored the mineshaft, which had more than 900 rails (895 mined plus a few more), considerably more than the previous record, 757 in TMCWv4; while not directly correlated to their size since whether a corridor section has rails is random I use this as a measure of the size of a mineshaft, which vary a lot more in TMCW than in vanilla (I've seen mineshafts with 10-500 structure pieces while testing a tool I made for the upcoming TMCWv5 that includes a listing of mineshafts by size. For comparison, vanilla mineshafts usually have 75-150 pieces based on Mineshaft.dat, which I disabled in TMCW to fix MC-33134, as there is no reason to save their structure data).
There were also 9 cave spider spawners, which along with their increased spawn rates and naturally spawning cave spiders (anywhere below sea level at 1/10 the rate of regular spiders, though they are more like 1/4 as common due to regular spiders having a higher failure rate die to their size), resulted in 154 cave spiders being killed, at one point more than any other mob and nearly a third of a total of 510 mobs; in the same session I also mined 5232 resources (only counting ore blocks, not drops):
This includes some stuff from a previous session; all the rails and cobwebs (from cave spider spawners) came from the current session:
The mineshaft then led to a quite large cave, including two large cylindrical sections rising high above lava level:
After this, I explored several networks of numerous large caves, many more than shown:
This is the same cave seen above:
This cave, which was nearly straight, was so long that it went out of render distance (as seen from each end):
There were many other relatively large caves, not exceptionally large for vanilla but a lot for the area I found them in:
After that I came across the biggest cave that I've found in this world, and one of the largest caves that I've found in any world (I analyzed it in MCEdit found about 153000 air blocks, about the same as the second largest cave in TMCWv4. This includes a few other caves nearby, while the caves in TMCWv4 were measured by themselves using a utility I made; the largest cave in TMCWv4 had about 251000 air blocks):
This was the first view that I got of the cave:
A view from a similar angle after I explored it; the other end disappears into the distance (you might notice that the underground fog is always black in recent screenshots; I partially re-implemented void fog (not the closeness part) and enhanced it so when below sea level fog is always black unless there is skylight):
The give an idea of the size of the cave, I had to increase render distance to 12 chunks (I normally play on 8 chunks out of preference even though I can go higher) in order to see the other end (taken from the same spot as the previous screenshot):
(I can't help but point out that at these settings the game is only using 135 MB of memory, while Mojang now allocates 2 GB by default for modern versions, which often use over 1 GB to just launch, and the server tick time is 2.1 ms, enough for over 20 players without server lag. Vsync is enabled but I get hundreds of FPS with it turned off, even at much higher settings, such as 20 chunks (note that the screenshot above no longer shows that Optifine is installed - I've completely replaced it with my own code, which is far superior and will be implemented in a public release of TMCW in the future, which includes many improvements to rendering, like fixing smooth lighting bugs (still not fixed despite a "new and improved rendering engine" in 1.15!), including smooth lighting on blocks like water (a Bedrock exclusive), increasing the biome blend radius from 3x3 to 7x7, actual darkness (these are with brightness on Bright but I rescaled the lightmap values so a light level of 0 is true, absolute pitch black; for comparison, In vanilla even Moody only goes down to 5% of minimum brightness - quite bad indeed (in addition to how ugly it looks when e.g. Night Vision is in effect). Many of these are things I fixed years ago (as part of a modified version of Optifine, hence why I never included them in a publicly available mod).
Also, this is a view of the cave in MCEdit:
As if that wasn't enough the giant cave lead to another cluster of large caves:
Here are renderings of the area I covered, from sea level down to lava level, and a cave rendering in MCMap:
Also, these are surface (night mode) and underground (layer 20) maps of what I've explored so far (click to view full size), after trimming away chunks without torches below sea level, which left 15930 chunks. On the surface map you can see a fairly large village at the northern end, which I recently found and the third one I've found in this world (there is another to the northeast of my base, near the center, and a very small (two building) village near the lower-right). Also includes is my map wall, which I've expanded to 5 level 4 maps (mostly just the center map has been filled in):
In addition, here is a surface rendering of the uncropped world in MCMap - even the first version of TMCW has far greater biome and terrain variety than anything you'll ever find since 1.7, especially for such a small area (this is still not every biome present in TMCW, which has increased since then; TMCWv5 will have triple the biomes and about twice as many "real" biomes (excluding minor variants):
There is something just so interesting about reading your posts. It's like a lecture but a fun one.
Anyway, hopefully once they add the cave update to the newer versions of MC it will be at least as good as yours. Caving is so boring these days I never do it. I want to walk around huge caverns and explore every nook and cranny to discover rare ores and gems.

Interested in playing on a long-term, complete vanilla world?
I saw a zombie in diamond armor for the third time in this world:
Also, while not particularly large (wide) the cave I found it in was quite long, being a smaller variant of large cave ("normal" caves vary in length from 80-128 blocks, "large" caves are 192 blocks long, and "giant" caves are 256 blocks long. For comparison, in vanilla caves vary in length from 84-112 blocks; in both cases "normal" caves branch at 25-75% of their length to form two narrow tunnels at 90 degree angles (this causes wider caves to have a teardrop shape as the main tunnel suddenly ends), while large/giant caves do not branch):
Also, I previously mentioned that I might make graphs of the data collected from each play session, which I did for a 100 day/session period, over which I mined 347596 resources, 325580 ore, killed 36092 mobs, and collected 550363 XP:
After nearly a month of playtime I finally found a way into the Volcanic Wasteland biome I found when I first played on this world, but never actually explored (underground), as I only go wherever the caves I'm exploring take me, aside from when I search for a stronghold early on. This is the rarest land-based biome in TMCW, with a 1 in 88 chance of being picked in this version; I found one in one other world, which wasn't as large as this one:
A view from above taken at night; lava lakes are more common higher up and the peaks are flattened so they are more likely to have lakes, simulating volcanic craters:
The terrain itself is generated as bare stone and is decorated with patches of gravel, cobblestone, obsidian, grass, lava lakes, and trees missing most of their leaves (later versions also include dead bushes and a leafless form of big oak which also generates in mesa biomes):
One thing that makes this biome unique is that magma cubes spawn, making them the only mob which naturally spawns in both the Overworld and Nether (in this version), as well as increased amounts of rarer ores, which generate higher up than usual:
This was the largest cave I found in it:
I also found the third and final stronghold in this world under it, only of a handful of worlds where I've found a stronghold while caving and only the second world where I've found all three strongholds by caving (including rediscovering the one found with Eyes of Ender):
Note that caves do not cut through strongholds, including in vanilla, where it is simulated by not overwriting air when generating the walls, but everything inside generates intact, including the portal room in its entirety. I also allowed them to generate underwater, years before it was implemented in vanilla in 1.13:
Strongholds in TMCW are more interesting and dangerous to explore due to spawners added to libraries (silverfish) and under the chests in corridors (skeletons, zombies, cave spiders, creepers, witches):
Also, one of the libraries was destroyed by a lava lake (this was patched in TMCWv4 by preventing lakes from generating around all structures except for mineshafts; notably, prior to 1.13 vanilla excluded lakes from villages, which was broken when they rewrote world generation):
Impressively, I found yet another zombie in full diamond armor just days after the last one:
Also, these are my stats for the past week, averaging about 200 more ore per play session than over a prior 100 day period, including about 50% more redstone and diamond (the 25th is anomalous due to mostly exploring caves near and above sea level, which are more common in mountainous biomes; Volcanic Wasteland also has the same amount of iron above sea level as below, while other biomes have 1/3 the normal abundance, so the amount of iron I found wasn't reduced. All the spawners on the 24th were from a stronghold):
I found two more enormous caves - and not only that, I found them on two consecut8ive days, the second one while exploring caves connected to the first, taking 4 days to completely explore them and their associated cave systems, including a third large cave nearby.
First cave; this is also the deepest such cave that I've found so far, about 50 blocks from floor to ceiling:
Here are renderings of the caves, including the entire area around them and the caves by themselves at the best depth for each one:
Today I had the most insane play session ever in terms of mobs - with 986 mobs killed, far exceeding my previous all-time record of 796, as well as an all-time record of 10561 XP gained in a single play session spent caving:
For comparison, this was my previous record for mobs; much of the difference was due to mobs other than zombies, including nearly twice as many spiders (less common in caves due to their space requirements; zombies, skeletons, spiders, and creepers all have the same weight in the list of mobs to spawn); 21 Endermen also has to be among the most I've killed before:
About two-thirds of the mobs were in a giant cave which was under the ocean, which helped contribute to the overall record number of mobs by limiting surface spawns; my previous record was also mainly due to a giant cave filled with mobs, as these caves are so large that mobs, especially zombies (due to their pathfinding range) can keep respawning on the other side as I slowly push my way into them (at times I only managed to place a single torch before having to backtrack to kill a new wave of mobs); the large flat areas also enhance spawning due to pack spawning mechanics:
Also, I've now played on this world for 32.7 real-time days and have mined more coal alone than total ores mined in any single world aside from my first world, with about 2.4 million total ores mined, followed by TMCWv4 with about 380000 ore mined (TMCWv4 has 22.46 days of playtime while my first world has 143.18 days):
This is also only my second world where I've explored more than one level 4 map, which may not seem that large to many people but I only explore the world by caving, except when I search for a stronghold and the area within 100 or so blocks of spawn:
Also, here is a table and charts of what I've done so far this month (ores mined, mob kills, XP gained per day/session); my averages have increased even more than from before, with an average of 3341 ore mined, 431 mobs, and 6075 XP gained per day (for comparison, over a 100 day period on the same world I averaged 3256 ore, 361 mobs, and 5504 XP, and in TMCWv4 I averaged 3141 ore, 351 mobs, and 5308 XP over 121 sessions):
This increase isn't necessarily because I've spent more time playing; on the 18th I mined 3461 ore in only 2 hours and 46 minutes - a rate of 1251 ore mined per hour, or 21 per minute, or about one every 3 seconds, which may be a record for the fastest I've ever mined during an entire play session (I've measured hourly rates of 1000+ per hour before):
I made an interesting discovery - two villages and a desert temple all within view of each other, the closest that I've ever two villages, as well as the first time I've found two in one day. This is also the first time that I've found a desert temple in this world, which have been rarer than other structures in my experience (they should be as common as jungle temples and witch huts in vanilla, but I've found about half as many in my first world, where deserts, swamps and jungles all have the same frequency):
Also, like many other things, desert temples are a bit more interesting than usual - there were two spawners, spawning zombies and skeletons in the upper area, and trapped chests in the lower area, with extra TNT under them (13 instead of 9); they can also generate the same as in vanilla (pressure plate and no spawners) or with both a pressure plate and trapped chests (a later version of TMCW replaced the wool with stained clay, as in 1.8):
I'm not much of a commenter, but it's neat to see the updates from your world. Now that I've stopped chasing the newest version, I've been staying on a single world as well, and it's funny how different that feels. I've been kicking around the idea of keeping a record myself, though (since I'm currently excavating a huge area for an underground "biome") it wouldn't be anywhere near as visually interesting, and I'd be tallying "double-chests of cobblestone excavated" instead of "ores collected and mobs killed".
TL;DR: we're quiet, but your readers are here and enjoying your posts!
