Simple, fun, guilty pleasure. About as deep as the kiddy pool though.
The graphics, as is usual with Team Ninja, are amazing. The girls looks amazing, the environments look great Typical Xbox goodness. That's all there is to say.
The voice-acting is all Japanese (unless you WANT to hear Dennis Rodman. You weirdo.) which is fine, because none of the character really have anything to say. "Hi." "Bye." "Thanks." That's about as far as it goes, basiclly. The default music is pretty old, and kinda annoying too. But, thanks to the handy-dandy Xbox hard drive, you can put your own music in the game. OMGPAPAROACHONTHEBEACH!!1 :DDDD Yeah.
Now, for the actual gameplay. It's fun. The volleyball game is simple with two buttons. One to hit the ball to your opponent, one to bounce it back to your gal-pal. You can move her around a little with the right stick, and move your girl with the left. Though, her A.I usually really sucks. The opponent A.I. is WAY better, and it advnces the more you play against a particular girl. Ex: If you play against Christie every day, but not against Hitomi, Christie will eventually get to that point where you can't beat her without pulling out a few of your hairs. At which point, you can go pwn Hitomi and her partner.
You can get different girls to team up with you, any of the lovely DOA ladies, in fact. And a first-timer to the series, and the first black girl, Lisa. All of the girls control and behave the same on the court (though some have a few noticable differences. The big girls like Tina and Hitomi hit the ball harder, but have less accurate aiming. Litle ladies like Kasumi and Ayane are the opposite of that. the middle-weights like Lisa and Christie are pretty well-rounded), but it's off court where the fun really is.
There are HUNDREDS of swimsuits to collect. Each girl has a large number of bikinis and such that are exclusive to her. You buy these with the money you get from playing ball or one of the mini games, and either keep them all to yourself, or try to give them to other girls. It's often more challenging trying to get the other girls to wear one than it is to beat her in a match. You can also tan your girl by playing in sunny areas, or resting on the poolside. Resting triggers a cutscene of your girl doing.. Girly stuff. Swimming, playing, sleeping, that kinda stuff.
Alot of them retain their personalities from the game. Ex: Christie is mean and doesn't care if she hurts your feelngs by rejecting your gift. )': LeiFang is nice and will take pretty much anything. (: Sometimes, if you're lucky, the target of your affection will send you one of her outfits. It's fun trying to get your favorite DOA girls to exchange swimwear. But Helena's suits suck, so don't bother with her.
Personally, I like trying to get Tina to wear stuff from the smaller girls like LeiFang and Kasumi or Hitomi. Good times.
You can easily spend days with this game trying to get the perfect bikini on your perfect lady. I sure did.
If you're not big on sports game, this is the sports game for you. None of that stupid.. Sporty stuff to get in the way of your fun.
