Just to add, the last game I bought from Game is faulty. Tried to install it last night, got CRC errors all over the DVD. This is a brand new game, still sealed. You don't get that problem with digital downloads, or at least if you do its easy to download a new copy. I have instead resorted to pirating a game I own, just to play it!
The high street has to adapt, they need to offer things you can't download. This for example was a collectors edition with book etc. that I would happily pay for, the shops need to see the internet as part of the town, and offer what they don't. You aren't just competing with the other local shops anymore. Amazon have pretty much killed any competition that the supermarkets hadn't already destroyed, you need to sell niche products to survive. To do that though you need to be brave, too many try to please all, and just end up stocking the same as each other.
