you can do a lot of the stuff you can do in minecraft. A few bits are not completed yet, and spawning of animals and mobs is quite frequent. Especially watch out for skeletons, in the latest update they are more acurate and agressive with their arrows. There are lots of abandoned mines, other interesting things like underwater houses and shipwrecks. the jumping magma blocks in the nether are deadly. there's lots of things to do in survival mode. It's not complete, although you can get to the end zone through the end portal, once you've found it. There are things you can't use like honey, sugar on it's own, and copper has one use (lightning rod), but it is quite enjoyable. I've spent many hours exploring, building houses and mines, and am currently experimenting with redstone items. more information and examples (separate to looking up minecraft info) would be nice; but there is an in-game crafting help which is handy. having persistant animals is nice and an improvement on hamlets quest.
