Not enough character development; with games like Blazblue it stands indifferent among fighters, but still entertains.
Visually, the game was very entertaining and had brilliant graphics, giving me a fun amount of Arcade grinding.
The problem with a lot of 2D fighter games (including this one) is the huge lack of character development, when so much care has gone into their character design; I enjoy cutscenes between/after fights to make the game deeper.
The gameplay is fine, if unfulfilling with the lack of special moves - the frames were smooth, the movement attractive and the graphics/effects brilliant.
In conclusion, I'd like to have known more about the characters and a larger set of moves to make this game something better; if graphics are your thing in fighters you won't be dissapointed with KoF XII.
I bought the game for £11 and in my opinion, that was fine; I wouldn't pay any more than £15 though.
