Really the only thing that probably couldn't be considered a dungeon is Goblin Grove.
And dark crypt ...
And spider cave ...
And owlbear cave ...
Maybe Hag lair ... ?
I don't know. The Hag lair has everything a dungeon should have. A story lead-up, exposition, a riddle, traps and finally, a boss fight and resolution. Normally that would be an hours long tabletop session, but as conversions to another platform go it's pretty good I think.
