i totally see where you're coming from. as an art student, boobs aren't a big deal (unless it's p0rn because i'll tell you my friend, that is not art)
anyway, dragon age probably isn't the best example. dude, somewhere in the middle, this guy tells me that sex is a straight up plot device that alters the outcome of the entire game....wierd right? and the box art has blood all over it, it was asking for an M rating and thank god it asked for it. the entire blood nudity whatever works. it's like a really damn good R rated movie; yes there's the word fuck a lot and theres a scene with boobs in it but it was one of the greatest movies ever made in history (i.e. THE GODFATHER PART 1)
anyway, here's why i think nudity is bigger than violence;
what do saturday morning cartoon shows like ben 10 have? violence, or parents and kids call action. cool stuff us boys love, like chuck norris beating the living s**t out of an asian mob gang in hong kong, or indiana jones punching a nazi in the face, that's friggin awesome. i bet parents would honestly show indiana jones to their kids, maybe not little kids, but kids, that's when i found out about it.
now throw some naked woman in there and what are parents gonna say? NO WAY IN HELL IS MY CHILD WATCHING THIS!!! now you see the problem.
sex in an issue that's very closed in america where as in europe it isn't. a friend of my dad's who was visiting from sweeden was talking to us about it. he said that women here in america wear a LOT more clothing than they do in sweeden (no surprise to me there, but now that i've heard it from a sweedish citizen i've confirmed it for myself)
action/violence is something no one cares about, as long as there isn't a gears of war 2 level of blood and it's only punching and cool car chases. not anything like hostage situations where people are crying their eyes out when there's a gun pointed at their head and they get their brains blown out anyway, i myself wouldn't want kids to see that, that's horrible.
my rant here is done, now i'm off to play halo reach where i will violently stab people in the back.
