More and more game developers are allowing their games to evolve by allowing end-users to modify the game. There were many mods created for games like Doom and Duke Nukem 3D, but Quake started a mini-revolution in mod creation with the accessibility of the Quake C programming language. Since that time, legions of fans have been adding modifications to Jedi Knight , Quake II , and Unreal . These mods can be as simple as changing the way an existing weapon works or as extensive as implementing a entirely new method of gameplay. The shear number of mods created makes this the most actively developed area of the Gaming Community .
New weapons represent the largest group of mods.
Some, like homing missiles, are only minor tweaks of a game's arsenal. Others are blasts from the past, like the BFG 9000 from Doom. Most are entirely new creations that expand the game dramatically. Sluggo has a special place in his heart for teamplay mods, especially CTF, and does a fine job of covering them. At one time, Quake C Archive hosted the largest collection of Quake C mods available on the internet.
