Honestly, not half bad.
DOAX2 is shameless. Utterly, completely shameless. There is no other reason to buy this game except to look at the crazy breast physics and the gorgeous women. Right? Wrong. In all honesty, this game is pretty fun. The volleyball is way to shallow (only A and B... please), a few of the minigames suck (read: pool hopping), the casino is awful, the story is lackluster, and the whole relationship/gift giving deal is kind of silly. On a final note, the achievements are poorly done and take way too much time and effort for a game that is supposed to be this lighthearted. Now then, on to the positives. The graphics for everything are great. Team Ninja is always on the cutting edge of graphical technology, just in this case there is some ridiculous amount of polygons in a breast rather than in a shruiken. Some of the minigames are quite fun- the butt bump is hilarious, the water slide is pretty challenging (seriously), and the beach flags is not half bad (I know its just button mashing, but I keep coming back for more.) The highlight of the game is definitely the jet-ski races. This is the most fun I have had with water sports since Wave Race for the Nintendo 64. Seriously. Finally, all immaturity aside, it really is fun to play this type of game with gorgeous women much the same way playing Tomb Raider with Lara Croft is infinitely more fun than it would be with Larry Croft. DOAX2 is the perfect game to mellow out with in between your hardcore shooters and racing games. It is unlikely that you will feel any sort of intense adrenaline rush at any point during this game.
I have to be honest, this game really has a rather wide appeal. Its lighthearted, easy, simple, and fun. You will definitely pick out a favorite character in no time and get wrapped up in gathering all of her items (ahh Hitomi... :D) and suits. This game might not win any awards, and it definitely is not revolutionary, but it is worthy of a place on your shelf.
