Quake 4 Announced

Volumetric fog. This was not done in a video game before Q3
Delta packets - Q3 was designed from the ground up to be a networked game and innovations such as delta packets resulted from this.
Ballistic parametrics - Instead of bullet positions being relayed over a network, Q3 relays position, velocity, acceleration. Remember physics? This is enough to describe the entire trajectory, making for a large bandwidth saver.
Linux (thank you Loki) - It took a *long* time for Q1 and Q2 to be playable in Linux. Loki accomplished this quickly
What else did I miss?

That's like describing golf as "swing-swear-walk". Quake or Golf: as a beginner it's chaos with random bouts of unexpected good luck.
But watch two good players in a rocket duel on a fast, jumpy map... it's as artful as swordplay, or as close as you'll get on a computer. They'll dodge and feint, probing for holes in the opposite's guard, suffering small wounds for better position, and then sacrificing the position to inflict greater injury.
It's hard to recognize innovation while it's happening. Before Q3, shooters were about aim and item management. Number three introduced technique as an integral game element.
This guy expresses the same point, better than I can. I put my words first anyway, because he's dead:
Nonono... Carbon is just a compatibility hack. Real apps should be build with Cocoa, but I'm sure Carmack doesn't need to be told. As we all remember, OpenStep (now Cocoa) was the original development platform for Doom and Quake. So when he says that MOSX is his "new" development platform, he really means "old".
Any sufficiently advanced civilization is indistinguishable from Gods.
