This has been an interesting thread. Popcorn and all, guys.
That said, my biggest problem with Team Ninja specifically is when they advertise Boobs where Boobs don't matter (https://www.youtube.com/watch?v=xbcMI0FjlBg). Anyone who actually buys in after a commercial like that is someone I don't want to know. Big Jiggle Tits in a Soft-Core Volleyball Simulator (or anything raunchier), while not 100% mature, is their business. I can just choose not to buy what I'm not interested in, and support what I am (and in the past, I actually have shelled out for DOAX games). But that should not be the selling point of a game in which you can do this (https://www.youtube.com/watch?v=7JHvyWA3WJA). If the female characters all have Jiggle Tits while demon slaying, I'm honestly still okay with that so long as focus is where it should be; the slaying.
I only note this because this thread seems to have been spawned in the wake of the conversations sparked by DOAX3, made by Team Ninja and Tecmo, and the above paragraph is why I've stopped supporting them for fundamental reasons.
More on the thread itself, I've never been bothered by boob sizes. I've seen girls with body types that -should- have huge sagging boobs be almost entirely flat as a board. I've seen girls with rail-thin figures have boobs disproportunate to her size (and her age; dear god this was chaperoning a high-school church function! A pool party, mind you, but still!), and just about every single combination allowed. Admittedly most of the time they don't always freely defy gravity and physics in staying both perfectly perky and round, but at the same time that's both more time analyzing boobs in a video game than I think is entirely necessary (so long as the game is one in which sex appeal pushed into your face is the main point), and a bit silly considering all of the other crap that gets pushed in gaming.
Sincerely, you know what I'd like? I'd like to see a game in which we do basically everything in the DOAX series, but with a bunch of hot, skinny yet muscular beef-cakes with abs you can cut meat off. Would be fun for a change to enjoy/exploit the male body for fun, rather than just the female.
That said, the world itself needs a new perspective. I think Yahtzee said it best in his secondary review for Bayonetta 2: In an ideal world, Bayonetta would stride into the room, legs akimbo, and start doing suggestive things with a gun barrel, but everyone would just roll their eyes at her and resume the orgy.
