Oh dear lord. I bought this last night, and now I'm trying my third world.
I already have a glass porched MAN CAVE. Or rather, DOUG CAVE. I've dotted the terrain with torches to guide me back to an underground cavern system where I found two Monster Dungeons (and their prize cabinets).
As a cocky show of success, I've set up a work bench and a stove inside of the Ex-Monster Lair #1 that I discovered, so that I can make torches, build ladders, and smelt steel and iron.
Anyone else try this game?
I'm there as Skaramine.http://www.minecraft.net/
It's playable free, but also, you can buy the alpha now and never have to buy the Betas or the professional version.
It's $12.99 American, 9.99 Euro.
