I picked up the GURPS 3e Basic Set last weekend for 99p in the Forbidden Planet sale. There was a pretty big selection of RPG books for sale at that price. I can't work out if this is a sign of End Times or not - this was obviously a clear-out of a large amount of unsellable stock, which indicates a plummeting market for RPGs, but on the other hand most of the books on sale were of the godawful tripe variety (a shitload of supplements for the Babylon 5 game, for example).
Anyway, I got the one thing that was worth buying, so either way I shouldn't complain.
I also took a gander at the proper RPG shelf, and was surprised to see some relative unknowns well represented on there - Mongoose Traveller, Mouse Guard, a few other rpg.net darlings. D&D 4e has also made its way into Waterstones, which makes it (I think) the first edition of any role playing game to ever be sold in a 'proper' British book shop chain. So perhaps things aren't all bad.
