Rumble Roses XX may leave little to the imaginiation, but its replay value is refreshing and underappreciated.
As far as the problems go, the most aggrevating one is definitely the lack of storylines for the single player mode... or simply the lack of direction period. As far as I know, there's no way to predict when you're going to get a title match, which can get frustrating after a while. I've played almost 60 matches with Reiko, and I have yet to fight the last character I won the title with. But eventually, somehow, you will get one. The PHM matches (or something like that) are really difficult to finish, but other than that, it shouldn't be too difficult to kick a little bootie. Another thing that's just flat-out annoying are the character intros for the Arena and Red Valley. Some aren't that bad. Some actually fit the character. But what's up with all this weird Japanese, "Pokemon" garbage for characters like Aigle? I mean, she's being followed by a huge M&M up to the ring?! Why?? The only ones that half-way make sense are the ones that are related to "American" characters. These other characters need to re-evaluate their intros. The beauty of it is if you hold down the L Trigger and press A when its on the "vs" screen and you're playing a singles match, your intro will be switched with the one you're playing.
I like the customization options for all the characters, although I wish there was more to it than there actually is. More costumes and more control over their appearance. (Instead of selecting preset hair, be able to change it to the way you want it, etc.) The "Superstar" versions of each character is also a nice little bonus, which also means another outfit you can wear... but only as the "Superstar" version of your character, and you can't make any changes to the outfit.
The game is pretty easy to pick up and get into... so even a beginner can button-mash their way to victory. The sounds are decent, and the graphics... well, you'll have to make your own opinion on that. Overall, I'd say its a strong wrestling title that can stand with any other... with a heavy side of sexual references.
