Revisiting the original DOS DOOM video game
I love this retro-game review of DOOM by Lazy Game Reviews. Of course, the latest version of the classic FPS just came out last week and while you may be more inclined to watch reviews of that game instead, this one is worth your time too I think.
Amazing things that I never knew about the original DOOM game are shown in this video. Like the box art and the fact that it was shareware (I either never knew this or didn't care as a kid). Anyway, just a nice little stroll down memory lane...
