I think that it's fine for game characters of both genders to be attractive, because, as a lot have put it, games are an escape. People don't want grim reality. But that is certainly not an excuse to not characterize a someone in a game. I also think people want someone they can connect to, a character that shows emotional depth and a cast that demonstrates an entire spectrum of personalities, not cookie cutter bombshells or cookie cutter space marines. The overly macho, gruff space marines are my biggest grief, oy vey, and I was just glad in Halo that Master Chief knows to just shut his gob. Or possibly he's just mute, either way big ups to Bungie on that one. Of course it's okay to have have busty bombshells be the centerpiece of your work, but it really gets on my (nonexistent) tits when developers try and fail miserably to characterize their cardboard cutout du jour because they thought maybe some depth would bring some maturity into some bland bloom-filled juvenile tits-travaganza instead of just owning it, and have fun with the 13 year old magnet they created and leave the dramatic characterization to the grown ups.
All I'm trying to say is that I don't think there is a fine line between trying to make a mature tale with a well developed cast of characters and the new bewbiesfest 69. It's a football field filled with broken glass, honey and fire ants between the two(Weird combo, I know)and trying to step into the other side will get you assf***ed three ways to Sunday.
Please point out the glaring flaws in my addtion, please, because I'm wirting this late at night with caffeine-shakey eyelids.
I know I left out the oversexualized male bits, just whenever I wrote tits add "and hulking biceps" into the horrible insanity I wrote as you read.
TL;DR - Nope there isn't one. Sorry
EDIT: Oh my god, I just read it and I'm all over the place man! First I'm all for integration of sexiness and characterization and then I'm all for leaving the two in seperate rooms. You don't know where I'm coming from! I'll leave it at that. It's effing late, I can't compose my thoughts right.
