Are you saying this because you really find this to be true or just saying it just because?
Because I find it true. Believe it or not, I take no issue playing female characters. In fact, I quite often do in other games. I play characters that I like their persona, flare and fighting style. Character gender isn't really a primary concern for me.
Hands down, Hayabusa is more fun than any other mother-fucker in the game. Had he been a chick from the beginning, I'd still be maining the same character. He's doing cool shit 24/7
After that: boom, it's Leon. No doubt. The simply brutality of the character and the satisfaction of overwhelming your opponent by sheer, unstoppable force is hard to match.
After that, it is actually a female character. La Mariposa. Her moves are flashy, intuitive and fun to do.
And after her is probably Tina.
Next I'd say it's Rig. His fighting style looks great and having practiced TKD myself, a lot of it kinda resonates with me.
Next in line I'd say is Akira (even though I suck balls with him). His level of execution makes each movement thrilling, and, and his vibe is serene but aggressive (much like Hayabusa). That drive you get dominating a fight is great.
I could go on, but long story short: the guys in general just tend to have the better fighting/playstyles to me. I don't play male characters 'cause they're male, I play them because they're fun.
