Build engine games in general seem to be built different (no pun intended), I think, because they tried to be realistic, so enemies are more bullet spongy, and mostly hitscan, and to top it off, environments are often tighter and more cluttered. Quake had basically empty rooms for the most part, with lots of room to maneuver, and while having a lot spongier enemies it had no hitscans so the gameplay loop is entirely different. No amount of one-liners (which are, admittedly, awesome) can change that. And the keycards are lot harder to spot! Especially in Redneck Rampage.
No one seems to point this out, they're just bungled together as le "old school boomer shooters", especially now with the new Build craze.
