DayZ, a game that's in alpha stages, has already sold 1 million copies according to creator Dean Hall. One million people have paid $29.99 to get early access to a game that's far from finished.
That's pretty amazing and considering how tough DayZ is to play, that's a great feat. DayZ isn't your typical zombie survival game as it seems bandits are the ones you have to contend with most of the time. It's got a steep learning curve, but there seems to be enough people out there to pony up the money to make it a huge success already.
It does goes to show you that PC gaming is alive and kicking, especially for a very hard PC game.
