We've become so used to hearing about how one movie, or the next, has gone on to become the highest grossing ever, in the history of man. But, what about the games, man, the games? 

Video games are now treated with the same hype, budget, and star power as any Hollywood explosion. Gone are the days of sweaty programmers coding sprites for a game no one will ever hear of. Hollywood celebrities are voice acting in games more and more, and it's only a matter of time before the gaming industry eclipses Hollywood entirely. Here's a list of the biggest selling games of all time. Just to be clear, not the most units sold, but gross revenue earned. Doesn't matter how many times you buy Ghostbusters on DVD, it's still not gonna beat Avatar in its opening weekend. We're talking about the dollars, all of them.
