Yeah, I admit that I roll my eyes at games like that, mostly thanks to two reasons. One, those breasts are stupendously big. Like, what the hell that's idiotic.
And two, and most importantly, is that outside of those boobs some of those girls look dangerously underage. And that shit ain't cool, not at all. It seems to be an endemic thing in anime character design and it really grosses me out.
It was even worse with some rich kid at my local geek hangout. He wanted to show off his homemade Magic the Gathering playmats and one of them had a risque anime schoolgirl tableau with even more obviously borderline-underage character design. There were some uncomfortable chuckles at it, but me being the resident Dutch-guy-who-speaks-his-mind just came right out saying "Dude, those are teens, that's goddamn creepy, what the hell?" And my friends gave me this "Y'know this guy has a point" looks.
So yeah, that stuff gets a no-no from me. Titillation is fine but for heaven's sake stop the 'innocent teens' bullshit.
