Source is a 3D game engine developed by Valve. It debuted as the successor to GoldSrc in 2004 with the releases of Half-Life: Source, Counter-Strike: Source, and Half-Life 2. It is most well-known for its usage by Valve, but the engine has been used both by small teams and individuals to create modifications of Valve games, and other studios creating distinct games, notably Troika Games' title Vampire: The Masquerade – Bloodlines. Valve continued to create incremental updates to the Source engine after its 2004 release, most of which coincided with games created by Valve. In the late 2010s, Valve created the Source 2 engine to replace Source, with it publicly debuting alongside Half-Life: Alyx. The Source engine is most well-known for its advancements in physics, AI, and graphics.
Doom WAD is the default format of package files for the video game Doom and its sequel Doom II: Hell on Earth, that contain sprites, levels, and game data. WAD stands for Where's All the Data? Immediately after its release in 1993, Doom attracted a sizeable following of players who created their own mods for WAD files—packages containing new levels or graphics—and played a vital part in spawning the mod-making culture which is now commonplace for first-person shooter games. Thousands of WADs have been created for Doom, ranging from single custom levels to full original games; most of these can be freely downloaded over the Internet. Several WADs have also been released commercially, and for some people the WAD-making hobby became a gateway to a professional career as a level designer.

Whirled is a virtual world website and video game created by Three Rings Design. Its Open Beta stage was announced at the Game Developers Conference in 2007. It makes use of Adobe Flash as an applet embedded into the website while also having pages of HTML and JavaScript in a sidebar to allow players to manage their friends list and browse various categories of user-generated content. The concept is comparable to the virtual worlds in the PlayStation 3 game Home and Second Life, while also incorporating aspects of feed-based social media sites like Facebook and Twitter. It pushes to make all content user-created, mainly with its approach to creative accessibility using Flash's affinity for 2D vector graphics and various web compatibilities to make it very simple for players to upload a wide variety of content using simple, conventional file formats. Some examples of this include uploading PNG files to create in-game objects, and MP3 files to create a music playlist for a player's room.

Based on Id Software's open stance towards game modifications, their Quake series became a popular subject for player mods beginning with Quake in 1996. Spurred by user-created hacked content on their previous games and the company's desire to encourage the hacker ethic, Id included dedicated modification tools into Quake, including the QuakeC programming language and a level editor. As a game that popularized online first-person shooter multiplayer, early games were team- and strategy-based and led to prominent mods like Team Fortress, whose developers were later hired by Valve to create a dedicated version for the company. Id's openness and modding tools led to a "Quake movie" community, which altered gameplay data to add camera angles in post-production, a practice that became known as machinima.
