The KoF games have always kinda been lost on me. I'm more of a Real Bout 2 fan than anything.
That being said, I enjoyed what little I played of 2002UM and 98UM, though BlazBlue-thorough tutorials would have been nice for those games, considering all the wacky systems they have whose purpose completely elude me. It boggles my mind that it has two fewer buttons than Street Fighter, and yet I find that game way simpler to play.
This game looks gorgeous though. I NEED to see Yamazaki and Rugal in that art style. (I would also accept Heidern and Brian Battler.) My main fear with buying the game is that they'll just release a better version with more characters down the line.
