Depends how you understand "the worst" - form e a glitched level where you can see distant rooms from a mile away, while monsters are stuck under the floor is probably worse than a bug-free level with very basic architecture. Andi t gets even funnier if the file was corrupted for some reason and starts exhibiting even weirder bugs :P

Well, yeah, id Tech 1 has a lot of nasty limitations, especially the impossibility to have a room over another room. It is possible to create some amazing tricks to circumvent some of the limitations, yet this takes a lot of skill and patience (and you have to pray it won't bug out).
