Wha'? They've already got one on Fargate and one (or is it still two?) in Meadowhell. Where are they opening it? Crystal Peaks seems like the obvious answer, but in my 12 years in Sheffield, I went there once, on my way back from work.
Edit: Currently out of the country, otherwise I probably would've seen them kitting it out myself.
I really do dislike Game. They should never have taken Gamestation over (the government shouldn't have allowed it). It's what's created this situation where the pubs and console manufacturers need a High Street presence for new stock, and Game are the only player in town. When the restructuring happened with the bankruptcy, the government should've come in and seen that an essential monopoly in high street video-games was a bad situation, and forced the new owners to sell off the extra stores to someone willing to open a competing video-game chain. As it stands, it's a symbiotic partnership between the industry and Game, and that's not good for the consumer. Either Game continue being an effective monopoly in video-game-only stores on the High Street, or they go bust, and the consumer loses a store-front and the industry loses a retailer.
