"For the average gamer, the initial learning experience with any unfamiliar 2D fighting game is almost always the same: who's who? That's to say, who's the Ryu/Ken of the game? Who's the "sonic boom" character? When you get down to brass tacks, just about every game in the genre -- and I'm talking everything from classics such as Samurai Shodown to digital abortions like Clay Fighter -- relentlessly doppelgangs Street Fighter II's basic character DNA. It's a comfort thing; if you understand how to throw a fireball or prep a flash kick, you have a rough idea of how to play pretty much everything else. But the folks at Arc System Works aren't hearing that. In a step that makes even their offbeat Guilty Gear games look tame by comparison, Arc pushes us well outside of that comfort zone and forces us to reprogram our decades-old fighting game logic with BlazBlue: Calamity Trigger."
