Hate is a very strong word. Character wise the game is great, but the strikers break everything in the game. Also the huge number of strikers bug me because if there wasnt like 100 strikers per character the game would probably have much better character sprites.
Kof 2k1 has horrible music and visuals, but has much deeper and less abusive gameplay (unless your playing as foxy or to some extent Maylee). Its a game that you would probably hate when you first see it, but when you play it for a while its quality shines through.
I actually like 2k quite alot, but 2k1 is just better.
