Soul Calibur IV, I flew through the game and done story with loads of characters and my CAF (F for fighter) is awesome. The tower of lost souls is sick I flew through that as well until I reached this one level (think it was like floor 52 or something) and it's nearly impossible lol but I'll just have a few tries a day until I complete it and then I'll keep on playing like the game addict I am.
I got TNA: iMPACT pre-ordered and will be getting FIFA 09 the day it comes out (hopefully) so those will be my games for next month...
