Quake III Arena, see here in the screenshot, cost $50 when it was initially released, and remained extremely popular for years after. Now you can grab a copy for free.

I hadn't heard about this, but is there any statement by id backing this up? If so, does this mean that the resources may be used in other projects that have been trying to replace models/textures/etc?
