My favorite recent games have been:

Borderlands for it's originality

Afro Samurai I just really enjoyed playing through that game

Call of Duty 4-6

BFBC2 I know it's a new game but they have really improved on the original and it has been a blast for the last few days.

Both Fables

"Well gotta go feed my 360 it's daily dose of DVD. It's hungry, it hasn't chewed up a CoD disc since last night...hope it doesn't try to eat me when I sleep..."

Hilarious. They are both really great systems that I truly believe would not be as good if it weren't for the healthy competition. I love that everyone says this PS3 exclusive is better. GOOD! That will only give someone more motivation to make a better game for 360 which will give motivation to someone to make something better for PS3 and we all continue to get great games. I love it personally. If the 360 and wii both died and all that was left was PS3 the gaming world would be in bad shape. Yes I would buy a PS3 if that happened but I am not sold that the quality of games would be as good all the time.
