Ya, I loved Eye of the Beholder too. Though I was lazy and never mapped anything, so I was always lost and just roamed all over the place. ha.
It was about the closest I could think of as an example too. I've not played a lot of Etrian Odyssey III, because I decided I wanted to start from 1. But I have explored a lot of the 1st level of the dungeon. It seems like it revels in the old school. Classic need of dungeon mapping, a decent amount of difficulty. But, at least in EOIII, I was able to have 1 character tank and the rest of the part was usually pretty safe.
