20 Years of id software
Gamespot has just posted a video featuring interviews with the founders of id software regarding the 20th anniversary, including some inside-information about the past and the future of the gaming company. It's quite interesting as it doesn't only deal with the developers' more ongoing projects but mostly with releases from the past - the true classics like Catacomb Abyss, Commander Keen and also Doom. The whole 30 minutes of video material can be watched at Gamespot's webpage. Take the time, it's worth every second.
