Big DOA fan here, hello. The DOA Xtreme games are... Yeah, just fan service. The DOA community (the competitive one at least) doesn't quite care for the sexualization of the females, it's just a cash-in, and oddly enough people missed it so much that there was a cry from fans to make another. It's just one of those things that makes DOA, DOA... That being half naked women that are well endowed. Actually, the normal DOA girl outfits aren't too bad, it's usually the
alternate costumes/DLC that can get a little too spicy. The gameplay is essentially almost a dating sim of sorts, but not...
You choose a girl to play as, play mini games, earn cash to spend on swim suits and gifts you can give to other girls to form friendships. I wonder what goes through the straight male's mind (or lesbian) as they play that... They probably are just there for the eye candy. It seems like a game younger girls would enjoy too, yet at the same time it's uber sexualized in every way. I don't really know about those games to be honest, other than the fact it's a way to make money off of the sexualization of women.
At least they're all 18, right.
