I'm sure some people must have heard of this, it's become quite a big deal in a short space of time.  Block building survival game from a single indie developer.  Anyone who ever played with lego will be right at home here.

Hint: You can download the client and unplug your internet connection to play single player for free (this is time limited I believe).  Multiplayer is where it really gets fun though.  Plus, if you play this for any length of time, I'm sure you'll agree this guy deserves your money.  It's still in development just now and the price is set to double on completion so it's a bargain (E9.95 / ~Ã,£7.50).

Bear in mind this is Minecraft Classic, a now rather-old branch of the code which is no longer being developed.  It lacks a lot of the features of Minecraft Alpha, the current in-development branch.  You can try Alpha for a limited time in offline mode by disconnecting your network access.
