You mean they haven't already entirely given up on PC games in GAME, Gamestation and the like? GAME especially, I go in there, there's about 20 metres of wall space, about 6 shelves per metre, ONE at the back is PC, of which 2 shelves are purely WOW stuff, 1 is mostly Sims, and about 3 are crappy budget stuff, some of which they still feel the need to charge £10 for.
On top of that, they still like to charge £20 or more for games over a year old, and silly money for new titles, generally £40 for a big title.
Even bypassing Steam, last year, the Wrath Expansion for WOW, £25 in GAME, £20 in Tesco (not even publicised as an offer), £18 on Amazon and Play. I think they purely exist as somewhere to sucker customers who don't realise you can buy games from places that don't have 'game' in the store name.
I'll give you the fact that Steam are pretty damn pricey too when it comes to new games, what's the deal in charging £40 for new titles when you don't even have to print up a box cover or burn a disc, never mind transport and storage, supplier and store cuts of the profit etc.
However, if you don't need games on the release date, you'll generally get a good set of deals a few months down the line.
(Still waiting for Witcher to go back on sale tho)
