Anyone who pays any attention to video game releases knows about exclusive pre-order deals for in-game content. Until a year ago, that content was a statue, a figure, a hat, or something we'd consider "swag" in the gaming world. That all changed when retailers and publishers started releasing codes for in-game content. It started off as a gold-colored Lancer for Gears of War 2, or a Warthog with flames on the sides for Halo Wars. While these were merely collectibles that changed in-game aesthetics, it has recently evolved to game-altering exclusives. I'm talking about exclusive characters or gameplay modes that could potentially change the experience of the game itself.
