from my memory of the time the whole promise of quake was that it was going to be a huge technological innovation. that’s what we wanted, that’s what kept my interest and had me playing the leaked alpha and buying on day one. this is an interesting perspective they have because quake was a huge success. nobody at the time thought it fell short of doom. so maybe it broke id’s internal culture, but it put them in a position to continue to succeed. quake 2 was the misstep, it just wasn’t that great of a game, or that’s how it looked from the outside
Quake 1 was an unbelievable tech breakthrough: full 3d, quakec vm, overall engine design held up really well. It was not a perfect game but it was ok.
I still hack on the engine and its derivations from time to time.
Quake 2 was a development of that, will a deep focus on multiplayer. And it won at that. As a singlr player game it was boring but LAN play was just amazing.
So quake 3 did rethink the engine but went all in on multiplayer.
As funny as it may sound but in the end, it is quake 1 that just keeps going thanks to its easy moddabilty.
