Minecraft+Amnesia

[Chilton]

If someone actually set up a server to build it on, id join in without a second thought - It wouldnt be able to be an exact replica, but some frightening halls could be made - Then all the blocks could be set to unbreakable, and we could lurk through the halls scaring random people who join...

Sadly, there aren't any good servers for Windows that can run with indestructible blocks, in alpha.
You could make it in classic but sadly there arent any torches etc. which would be helpful in order to make some nice rooms.

My guess would be to backup the server every now and then and ban every griefer who griefs the server.

BTW: I'm working on a Brute skin.

Well, that would make sense - An even better option would be to make it so that players (Not OPs, just players) cannot pick anything up - That would prevent griefing mostly, and keep any damage minimal.
