Pale, I don't think you understand how this works. Doom and Quake's source codes have been released to the public, which someone has ported to the Wii. You have to own the original game files to use the Wii ports, otherwise you can only use the free shareware version that's included, as it has always been. You don't just download the game itself with everything included (ie the retail WAD files) - *that* would be illegal. This isn't only legal to do, it's practically encouraged by id software.
