Quake (id Software)
By this point the name id Software was synonymous with the FPS, or “DOOM clone” as they were often called. Quake ensured that Carmack and co. would also become the yardstick by which all PC graphics technology would be measured. Quake was the first major game to showcase full real-time 3D rendering using the nascent 3D hardware accelerator cards. It also took multiplayer deathmatch out of the preserve of office and university LANs and online, thanks to the pioneering work of QuakeWorld and QuakeSpy.
