So here's an odd circumstance... I was watching a "true horror stories" vid on Youtube, and one of the stories involved two people exploring an abandoned school and going into the basement, where they encounter crazed homeless people.

Oddly, this awakened in me a desire to crawl some dungeons.

So, what are some favorite dungeon crawlers of yours? Particulrly of the first-person variety, like Eye of the Beholder or Wizardry (to name some more popular ones). In particular are there any you like but don't seem too well-known?
