It's tough CUZ--
-A lot of people are burned out on SF4 after months of play time
-BlazBlue just came out. It's awesome, but will it last like SF does?
-SF4 has more characters
-BlazBlue has less, but far more variety between them
-3D models allows for extra outfits, sprites just have colors
-SF4's controls are more relaxed, but BB only uses four buttons, so any controller works nicely
But the big thing here is that when it comes to online, BlazBlue SPANKS EVERYTHING. EVERYTHING.
