Quake and id Software were pioneering things we just take for granted now.
I remember playing QuakeWorld when it came out, on Linux, over a dial up modem. You had ping times of 200-300ms and it was playable. You have to remember at the time Doom and other games were LAN-only. John Carmack used to keep a .plan file with some really cool details behind Quake/QuakeWorld development. Check out Aug 02, 1996 for some detail behind the netcode[1]. You can read the future of gaming being invented right there.
