Basically it's an epic game, if you want more info click the various hyperlinks ^.^ P.s Its 100% free unless you want the alpha version. Heres a picture: http://internetaware.org/wp-content/uploads/2010/10/minecraft.jpg
I've played the paid version, it's actually a pretty fun game that's definitely worth the money. It's only like 13 dollars yet it gives hours and hours of fun. IMO the single player survival mode is more fun than the multiplayer, but that could just be me.
alpha is basically survival... you have a little ammount of time to build objects, chop down tree's to get wood etc, unlike the free one (where you have unlimited resources) it is all about making weapons and tools... Bundles of fun!
would be great to invest some money in that company....its amazing what ppl can do in it, sow a guy making Star Track ship! If u wanna buy it, buy it now otherwise prices will go up in next few months! Its only 10 euros!
Its a great game, and wow what that person built is amazing. I am not a creative person so its kind of hard for me to design something like that, I just find my self exploring for resources
Just to let everyone know.. Notch (The guy who made it) On the first day of alpha release got like $25k in his paypal...
he was one day more selling then Starcraft 2, i think he got more than 200 euros in a few days, tax takes a lot because he is from Sweden i believe!
