Why doesn't it? Seriously though, it just is much more interesting, whether it be style reasons, personal preference, or just for the sake of creativity. Chiefly, I'm one who like diversity in his gaming cast, and I love the way SNKP has been very daring with the character choices. I'd be a bit disappointed if all we end up with is a bunch of guys who have similiar body types, since XII and XIII have given me some of my favorite characters, from the ones who go aganist the usual molds.
It's much more than a "hur hur, they gotz boobz!" issue for me, I assure you!
You know what? That was a well thought out response, I can dig it. Truth be told, KOF is the only (or one of the only) fighting game series in which I can pick some of the females, sometimes as a team, and not feel like some jackass is going to judge me for picking only female characters due to pre-conceived negative notions. Don't get me wrong, I like boobs, but I look at, say, Mai differently as a 31 year old male becoming-casual fighting game fan than I did back in 1992 as a 12 year old fighting game preteen with body and facial hair already in tow. I can pick King, Whip (if I bothered to player her), Vice, Mature, Vanessa (see Whip), Mary (see Whip), Leona, Xiao Long (yeah, I like her), Misty (bet you all forgot 'bout her), and Chae Lim. Mai/Yuri/Athena? I'd rather they'ed get Kaiser Waved off the stage.
