(You know, in Phylomortis : Avant-Garde the first battle against a slime was as hard as a boss fight, and the first dungeon was a rather twisted tower where you had to solve really tough control panel puzzles involving triangle rotations and stuff like the Fibonacci sequence. The monsters were very tough, too. So there are probably "first" dungeons that can beat the Mosquito Swamp in terms of difficulty, but... not in commercial games?
