What kinds of maps did you guys (dis)like way back when?
Desert was probably my #1 hated map, just due to how ridiculous the cave-flag area portal was combined with a dc 127 locker.
Caverns stands out to me as infamous for its short-range capping which made powerleveling ridiculous if you were able to reliably cap.
I really liked the underdark map without the gates (I think there were 3? don't remember the particular name) and also the hell-dungeon one.
Confussing walls also holds a special place in my memory due to its spelling.
Sadly I don't remember all the map names 100%. Maybe someone with better memory has a list!
