Carl Williams writes, "Doom. Anyone reading this that has never heard of this iconic game is probably on the wrong site right now. Seriously though, this is an iconic first-person shooter (FPS) that helped push gaming on PC’s forward quite a bit. Doom could not have been released at a better time as at that time, console gaming was eating PC’s lunch. Id Software had a hit on their hands and they knew it. They made sure to allow fans to make levels and modifications to the game, something that has extended the 1993 FPS’s life well into the future. One such mod is Brutal Doom, which is up to version 21 now."
