Rogue Entertainment was a computer game developer based in Dallas, Texas, which was active in the late 1990s. Rogue officed in the same building as id Software, and all of their games used game engines created by id, and two of their games were expansions for id's Quake series of games. Many former Rogue employees moved on to Nerve Software after Rogue closed. http://en.wikipedia.org/wiki/Rogue_Entertainment
