Choose miner, woodcutter, fighter or creative.
as a miner you will get a house some stuf and a mine.
as a woodcutter you will get a house some tools and trees
as a fighter you will get a little fort and you have to defend yourself against monsters
(monsters that normal spawn and extra: zombies, skeletons, spides, witches and sometimes a blaze)

if you choose creative you will be creative.

Good luck!
