most of the minecraft challenges that people come up with are long and tedious, but what about one in hell? it's probably been thought of already, but search didn't say anything. anyway, here goes:
Turn alpha into survival :biggrin.gif:!
pretty much surviving in hell. Really creative, isn't it? anyway, pretty much like it sounds. When you go into hell, drop all your stuff next to your spawnpoint so you can find it if you die. you go into hell, with nothing but your bare hands, and try to live as long as you like. i'm not sure if torches/lanterns make mobs be unable to spawn, cause if they don't you will have to be nomadic, without a base. cause the point of a base is to be safe.
but if they do, please don't just hole up in your base waiting therefor a record to be set - thats not fun, and certainly not impressive.
(please don't remark on grammer stuff, i'm on holidays and my brain power is 0)
