Just been into comet and seen a whole load of bargains in the gaming section. I can't remember them all, so I'll just list what I can to give an idea.
XBOX 360 - Mass Effect, FIFA Street, WWE 2008
PSP - KillZone, WWE 2008
PS3 - Condemned 2, Sega Superstar Tennis, Sega Rally, Viking
PS2 - Buzz Hollywood & Pop Quiz bundles including the buzzers
Wii - Harvest Moon
Loads more I can't remember :P
Also some accessories for 99p that looked pretty good. A couple of DS cases, and a PSP grip dock thing with power booster.
I think I had the last Condemned from the Romford store, but they had loads of the rest and Mass Effect for a fiver seems a great deal to me:D unfortunately my xbox is broke and I'm having a hellova hard time getting it fix even under warranty :(
