Soul Calibur 4
I got this game about two weeks ago and man is it addictive. I love fighters and I love me some Soul Calibur ever since 2 on the cube with Link as my main man. Now it's even better on the 360 with some hella good looking characters and fighting action. What's even better though is the Create a Soul option. This lets you create your own character in a sort of dress-up for men situation where you can make them into whatever you desire. It's a little rough, but I've gotten a good Power Girl, Huntress, Black Canary, Beastmaster, Drizzt, Elric, Worsel, Choker, Mixmaster, G, Faith, Parallax, Kyle Rayner, Guy Gardner and more. Yeah, a lot of the characters that aren't fantasy to begin with have to be created roughly with medieval weapons and armor, but it's amazing how close you can get to whatever you want. Check it out. Seriously. You'll spend more time creating than fighting at this rate.
