As the title says really, I managed to pick up the PC version of Flatout Ultimate Carnage for just £3.98 yesterday from GAME. I'd imagine that this is stock that they'd like to clear in the New Year Sale, but rather than being an awful game, I believe it is quite highly rated, (e.g. PC Zone rated the game at 81%, PC Gamer at 82%).
I've had a look at the GAME website and it still seems to be priced at £14.99, so this may be an instore only deal.
Got to be worth a look if you're near a branch of GAME!
