I was just reading about that game Minecraft which I had tried for a few minutes a while back and the dude has made $4 million dollars off it so far! WHOA! Here's the article I was reading:
5 Minutes of Minecraft
I know people have made amazing things inside the game (on YouTube some dude made a scale model of the USS Enterprise in Minecraft - friggen insane!) but it has never clicked with me. Kinda blows my mind though and it's cool to see 1-man teams making it , even when they never expected it.
