I go in Tesco around 11:30-12pm after the gym and I happened to be there for Fifa, Black Ops and GTA and the queue would be easily 100 meters long from the game counter down the full length of the extra store, up the aisle next to it and half way down the next.
People had like cases of beer, bags of crisp and snacks.
For Fifa I heard 1 guy all happy he got the game but was aksing where the xboxes were in the store.
I own an top end Alienware M18x gaming laptop (dual x80 GTX graphics, 32gb Vengeance Ram, Extreme Unlocked i7 processor, all overclocked to buggery) and I wouldn't even go stand in a queue for a game, time for a check up from the neck up if you ask me.
