The slimes are there because slime chunks still exist in superflat. Obviously it's meant for creative. Get some brains, who would want to play survival on a completely flat map?
Last I checked I had brains.LOL From what I've seen a lot of people are playing flat maps in survival. The first thing I did was start a Millenaire village without having to fill in water or level hills. Unfortunately the map is too shallow as the quarry they build is deeper than the ground. I deleted that world and made a large 20 block high area first and the village built great. I would love to experiment with building on a flat map in survival.What's wrong with that?As for the slimes since they left out everything but dirt and bedrock they could have left out slime chunks too.They left them in for a reason.As well as all the other mobs. It is nice to have a flat map to build up anyway you want whether in creative or survival.
I love superflat. More than default actually. It's a real test and I like that. I like looting npc villages instead of mining. And you can start a tree farm if you find a sapling. I already have a mini forest, a mob grinder, a cobblestone generator and infinite water. But different biomes would be nice I suppose so I could actually get glass bottles for my brewing stand (I killed a blaze for nothing :angry.gif: )
I actually like to create a superflat map for survival every once and a while. I play it on hardcore and go find villages. In villages you can get a lot of bread and wood off the farms, and I often destroy churches (sorry!) for cobblestone. Also if a village has a fordge, you can find tressure inside the building. Often times you find iron but sometimes you can find saplings and stuff.
Surviveing on superflat is actually a lot easer then it sounds, you just have to stay on the move.
