It was made for pure nostalgia and fun, letting people play their favorite Id generation; and is also legal, unlike Q2:Generations.
Generations Arena is currently under development for 1.0 which will introduce advanced animations (Doom reloading his Super Shotgun, Ranger swinging his axe etc.) currently Generations Arena is a playable beta (is compatible with OpenArena, as long as you have a patch which can be found in the OpenArena wiki).
