I loved the original Doom when it came out in 1993, and I still play it occasionally 25 years later because the modding community keeps adding to and changing the game to make it new and different.

Whether it's the legendary Brutal Doom mod that just makes it more fun to play, or mods that make it play like Wolfenstein 3D or Call of Duty, someone out there is always doing something wacky to Doom to make it worth revisiting.
