Minecraft

Found out about an awesome game today, it's called Minecraft.

Check it out: http://minecraft.net/

What it is, is a first person casual game that you build stuff with blocks. Like Blockland, only no where near finished, and there is only one block size. You can play by yourself or online multilayer. There is a gamemode of survival, which you, survive, duh, and it becomes a first person shooter type thing, not multiplayer though, yet.
