Why They and Their Games Rock

 * 1) They were behind many great franchises, such as Doom, Quake, Wolfenstein, and Commander Keen.
 * 2) They're responsible for creating the first-person shooter genre with Wolfenstein 3D and further popularizing it with Doom and Quake.
 * 3) Their game engines, the id Tech series, revolutionized 3D graphics, texturing, and functionality. Quake engine specifically was the first 3D engine for an FPS game and inspired other or forked engines like the GoldSrc engine.
 * 4) It's worth noting that, whenever a new id Tech engine is built, the previous one is released under the open-source, thus allowing upcoming developers to use their engine to make their own games.
 * 5) They've helped popularize online multiplayer with Quake.
 * 6) Their games are known for their massive modding communities, especially Doom and Quake.
 * 7) Unlike Activision, they do handle criticism and also try to learn from them.
 * 8) Doom (2016) helped bring first-person shooters back to their roots with many Indie developers nowadays making their own retro shooters.
