I'm playing Sudeki right now. (I should probably insert in here that I got it from the MS Retail Traning Program @ $5 shipped.)
It's good. The combat is cool, the voice acting is *decent* (please, before you say it sucks, go play the first Resident Evil on PS1 and use it as a basis for comparison). The storyline is a little weak right now, but I honestly won't care if it picks up at all. The combat really holds the game together. The worlds are pretty and the audio is just amazing. The menus are dead sexy, too. Neat level up system (although it is pretty standard) and feels sort of like Diablo II.
Rent it and decide for yourself. I enjoy it, but I also enjoy paying $5 for it.
Hope that helps.
