I think Mr. Woo needs to drop the spin doctor act.
This will doubtlessly never be read by anyone that mattered, but I think he misses the point that if I'm buying a game that touts the romantic options as a selling point, and honestly the Mass Effect series has done this from the very beginning as a way of generating hype, I expect eroticism appropriate to it's rating. With an M (or R) rating we're in "erotic thriller" type territory here, and if I don't feel a bit titillated by the sex scenes I have a right to feel disappointed by the product. Now if this game was a teeny romance with a 'T' or 'G' rating, I could see the arguement. But this *IS* an M rated game, and I don't expect it to pull punches.
I guess the big problem is that all pathetic comments about being "able to handle sex" which seem like something kids would ay whenever I hear it, the bottom line is that us adults like our erotic escapism which is why it sells so massively even when it's not outright porn. This applies to both genders. Movies like "Wild Things" were successful enough to spawn two sequels for example. Try and sound profound and mature all you want on the subject, that's simply how things are.
I think the big problem is that people keep thinking "finally we're going to see a real game oriented at adults that incorperates sex and eroticism into an overall game experience without turning into some non-stop hentai-type sex farce". The arguements really aren't about the amount of sex, but the quality of what is there. Nobody is looking for another adventure of Lane Masterdon, or Brad Stallion (and his spaceship 'the big thruster').
Bioware can beat around the bush all they want, but the only reason for some of these girls to put on more clothing than they wear normally to have sex is censorship, or fear thereof (referance to Dragon Age here actually). The issue here isn't the audience, and as much as Bioware tries to retaliate by making people look/feel awkward over making this point, the bottom line is that they have been messing up.
Of course honestly I suspect that Bioware (like other companies) lacks the guts to actually push the envelope, and would rather go to making "T" rated games than try and make real "M" rated titles... and in the process leading a charge that has the entire industry quaking with fear as they all wait for someone else to take the risk.
