Didn't PaRappa score the babe in his story? Kratos had a wife and a daughter. Nariko had a... well, a father. Fat Princess gets points for having more cushion. Who can tell what's under that mask, other than the enchanting voice Radec has? A lot of people also seem to have a sweet tooth for Sweet Tooth. The man is on fire, after all.
More than just sex appeal for the hetero male, I don't think this fighting game is merely about whether the characters are attractive to the player. More so it's about selecting your favorite (or most desirable) character from a PlayStation legacy and then pitting them against other scrawny or bulky brutes the likes of which you may or may not be all that familiar with. But maybe, just maybe, you'll want to dive into PlayStation's history books to experience these games for yourself.
