Metal Gear's been tacky in this regard for awhile. It was funny in 3. "Oh haha of course the boss is looking at Eva and of course a feme fatale has giant cleavage!
But in 4 you had strange camera angles on not just the skin tight Beauties , but even on Mei Ling's ass as she comically dropped something during her briefing. Oh is'nt she so cute! Hell, there's giant cleavage Naomi. Remember her, the doctor who was basically wearing a sweater in 1? Not only does she have cancer, but she's got a giant rack now too and she's not afraid to show if off!. Hell, now the sweater's on Rose, who won't bore you as much because you can shake her boobs as powered by Sixaxis!
And in PW there's entire character who all I can remember about her is that she's randomly in the forest and you can play with her boobs.
Quiet's outfit is dumb. Why is a Sniper in a desert even wearing stockings? Hell I can deal with her having little up top, because fine you can justify it because it's hot or something. The stockings are dumb and I don't see the point, it would even make more sense to just wear short shorts or something. But whatever, MGS is a series that lost most of it's dignity a while ago anyway.
And I don't mention the ACid games, because those a strange anyway so I don't care about the fanservice in 2.
But Fourtane's outfit seems just as dumb. To be honest, I never saw her as sexy or anything. I don't think that was the intent as it is with Quiet seemingly. But still why is a girl using a railgun basically in a swimsuit? I have no idea and in general I don't even bother to question what comes out of Japan anymore.
