Main article: Quake (series)
On June 22, 1996, the release of Quake marked the second milestone in Id Software history. Quake combined a cutting edge fully 3D engine with a distinctive art style to create critically acclaimed graphics for its time. Audio was not neglected either, having recruited Nine Inch Nails frontman Trent Reznor to facilitate unique sound-effects and ambient music for the game. (A small homage was paid to Nine Inch Nails in the form of the band's logo appearing on an ammunition box.) It also included the work of Michael Abrash. Furthermore, Quake's main innovation—the capability to play a deathmatch (competitive gameplay between living opponents instead of against computer-run characters) over the Internet (especially through the add-on QuakeWorld) seared the title into the minds of gamers as another smash hit.

In 2008, Id Software was honored at the 59th Annual Technology & Engineering Emmy Awards for the pioneering work Quake represented in user modifiable games. Id Software is the only game development company ever honored twice by the National Academy of Television Arts & Sciences, having been given an Emmy Award in 2007 for creation of the 3D technology that underlies modernshooter video games.

The Quake series continued with Quake II in 1997. However, the game is not a storyline sequel, and instead focuses on an assault on an alien planet, Stroggos, in retaliation for Strogg attacks on Earth. Most of the subsequent entries in the Quake franchise follow this storyline. Quake III Arena (1999), the next title in the series, has minimal plot, but centers around the "Arena Eternal", a gladiatorial setting created by an alien race known as the Vadrigar and populated by combatants plucked from various points in time and space. Among these combatants are some characters either drawn from or based on those in Doom ("Doomguy"), Quake (Ranger, Wrack) and Quake II (Bitterman, Tank Jr., Grunt, Stripe). Quake IV (2005) picks up where Quake II left off — finishing the war between the humans and Strogg. The spin-off Enemy Territory: Quake Wars acts as a prequel to Quake II, when the Strogg first invade Earth. It should be noted that Quake IV andEnemy Territory: Quake Wars were made by outside developers and not Id.

There have also been a few other spin off games such as Quake Mobile in 2005 and Quake Live, an internet browser based modification of Quake III. A game called Quake Arena DS is planned for theNintendo DS. John Carmack stated, at QuakeCon 2007, that the Id Tech 5 engine would be used for a new Quake game.

Rage

Todd Hollenshead announced in May 2007 that Id Software had begun working on an all new series that would be using a new engine that is currently being developed by John Carmack. Hollenshead also mentioned that the title would be completely developed in-house, marking the first game since 2004's Doom 3 to be done so. At 2007's WWDC, John Carmack showed the new engine called Id Tech 5. Later that year, at QuakeCon 2007, the title of the new game was revealed as Rage.

On July 14, 2008, Id Software announced at the 2008 E3 event that they would be publishing Rage through Electronic Arts, and not Id's longtime publisher Activision. However, since then Zenimax has also announced that they are publishing Rage through Bethesda Softworks.

On August 12, 2010, during Quakecon 2010, Id Software announced Rage US ship date of September 13, 2011, and a European ship date of September 15, 2011. During the keynote, Id also demonstrated a Rage spin-off title running on the iPhone. This technology demo later became Rage HD.

Other games
During its early days, Id Software produced much more varied games; these include the early 3D first person shooter experiments that led to Wolfenstein 3D and Doom — Hovertank 3D and Catacomb 3D. There was also the Rescue Rover series, which had two games — Rescue Rover and Rescue Rover 2. Also there was John Romero's Dangerous Dave series, which included such notables as the tech demo (In Copyright Infringement) which led to the Commander Keen engine, and the decently popular Dangerous Dave in the Haunted Mansion. In the Haunted Mansion was powered by the same engine as the earlier Id Software game Shadow Knights, which was one of the several games written by Id Software to fulfill their contractual obligation to produce games for Softdisk, where the Id Software founders formerly were employed. Id Software has also overseen several games using its technology that were not made in one of their IPs such as Shadowcaster, (early-Id Tech 1),Heretic, Hexen (Id Tech 1), Hexen II (Quake engine), and Orcs and Elves (Doom RPG engine).
