Having spent about an hour or so playing Rumble Roses XX, I can say that if you like wrestling games and well-endowed women, then this definitely your kind of game. As for the reviews giving such low scores, I have two issues with things they keep harping on:
1. Comparisons. They need to quit comparing it to the original Rumble Roses. They assume that everyone has a PS2 and must have played it. The closest I ever had to owning a PS2 was when I bought two of them at launch to resell. I never wanted one and never plan on buying one for myself.
2. Sexuality. According to the reviewers it's mainly marketed at 14 year-old boys with raging hormones and gets kind of embarassing after a while. They probably just got embarrased cause they started sporting wood when playing in front of their co-workers.
I actually find myself laughing at times because it's can seem a little cheesy. But that's alright because the game doesn't take itself seriously and that is what I think Konami was shooting for: a game that's easily accessible, has hot, big-breasted women and is just fun and funny at the same time. As for other girls playing it, my wife doesn't care one way or another how the character is dressed (or barely dressed). She just hates playing with me because she doesn't like to lose
