Just to update you, I've been playing a game called MineCraft. Personally I think the game is very very awesome and you should check it out if you haven't, its still only in alpha stages, so its a little buggy but its still a great game. Its also cheap and you get it half price (For Ever) if you buy it in the alpha stage (NOW).

You might find me on there, its TheDarkCube >_> but I don't play the multiplayer much
