Don't forget the bonus characters and bosses to unlock.

You get the seven NGBC characters, plus the unique mid-bosses like Silver and Gai, who plays completely different from everyone else in the game.
I use a lot of characters, but tend to gravitate towards Eiji (he's so awesome), B. Jenet, Tung Fu Rue, Kim, Elizabeth, Yuri, and of course Mai, although since she is the NGBC Mai, she's going to be different than what you guys are used to. I gotta get better with Duck King.
Damn, this game is ugly. Why won't they use high-res like Guilty Gear?
SHUT UP SHUT UP SHUT UP KOF XI IS YOUR GOD, MORTAL. BOW DOWN TO YOUR SAVIOR.

I"ll wait for KOF12 then. Unless they make a port for the PSP.
Don't wait. This game is way, way, way too fucking good to pass up on. And you guys are getting it for a steal at $15.
