If you date Andy, do you have to fight off attempts on your life by Mai?
Good point, Andy's route must be the toughest in the game - getting stalked by a clingy jealous ninja trained from birth by a family of ninjas would be pretty tense.
The game could do with a better title like The Prince of Fighters, but hey, I've been playing SNK fighting games for the story for years, I'd gladly play another genre if it fleshed out the characters further even if I'm not the target audience.
If they eventually translate it...
