Hey! So I was torn between the two versions of the map- the Legacy version was more fun, but the Comet Observatory version was bigger.
So I decided, why not combine them?
So I created a custom version of your map, based on the newer version but designed to work like the Legacy version.
-Changed a lot of the chests back to their original loot
-Redid the gamerules to match the Legacy version
-Changed the map to a Plains biome (to let mobs spawn)
-Replaced the heavily exploitable iron supply that is the Engine Room dome and walkway with Polished Diorite (looks the same, but is not exploitable)
I can email it to you if you're interested. There are no downloads for it, so if you hate it, I can just keep it for private use.
Let me know what you think!
