I see very often when people discuss their issues with map design of DOOM II they tend to bring up Sandy Petersen a lot. Just saw it now again. "I feel like DOOM II has way more problems with level design than any other DOOM game. All those Sandy Petersen maps lmao." It's really strange to me considering Petersen actually made more maps for the first DOOM game than the second. 19 out of 27.
Btw, Sandy Petersen's Quake maps are my absolute favorite of the entire game. Could have used a few less Spawns, but otherwise I feel like they are a pinnacle of Quake's otherworldly abstract architecture.
@dosnostalgic agree and I love how the game gets weirder with each episode, culminating in the totally bizarre episode 4. The architecture in quake really is something else.
