Well I'm female. I didn't buy this game to check out ladies' jiggling boobies. I can do that by standing infront of a mirror and jumping up and down.
Personally, for such a sexual game, I find it very girlie. A massive part of it is going shopping and making your characters look pretty. That's probably why I play it.
Having said that, even I admit it's not a very good game. The volleyball is very simplistic, the mini-games are even blander, and the overall gameplay is EXTREMELY repetitive.
I mean, you can't even trade your "memories" (photos) over Xbox Live. Pure laziness on the developer's part.
I know this game hasn't sold well - in any country. I'll be surprised if we see a DOAX3.
