Next-gen finally here.
The balance of the characters is fantastic in that any advantage I was able to find with a given character could eventually be nullified by another character's strengths. The fights can invite my methodic, strategic style, but cunning stunts of quick-fingering are also rewarded. Great fun.
DOA4 online wasn't the smoothest XB Live experience I've had but it's good enough to be fun and interesting. Fighting games were made for Live as far as I'm concerned, the ability to go mano-a-mano with people all over the world? Awesome.
