I am of course talking about the amazing fan fiction written by Nick P (not me). Also known as Spineless-Mush over at PortalForums.net. This book is simply called DOOM and is, as you guessed, based off the Doom universe. Through the upcoming years that eventually lead to the release of Doom 3, I read a bunch of fan fictions based off Doom. And while the Doom universe itself lacks any real story or dept, it does contain some of the coolest monsters and environments I've ever seen in a game (or movie for that matter). But most authors of these fan fictions couldn't put these aspects into a dark, demented, engrossing, and most off awesome story that Nick P. wrote.

I like to get nostalgic sometimes.  What I'll do to bring back memories varies from time to time.  This time though it was my old PC game manuals.  There are some good ones in there.  Some that I spent hours reading and learning from.  A lot of these games were out before the Internet was around, so all you had was their manuals to help you out.
