dtgreene: I don't pay too much attention to the step sounds, though I do note that, if you have a Levitation spell active, the sound changes to a "whoosh" sound.

The dungeon environments aren't that interesting, unfortunately. They do change every 3 floors in Shiin's Dungeon, though I haven't yet seen 10F so I don't know if that floor has a unique appareance. (Actually, I've seen that floor in videos, but don't remember it.)

The sequel, only available in Japan, looks like it has some more interesting environments, including some outdoor ones. (I'm hoping that XSEED ports and translates the sequel; I think they said they might if this game does well.)

(Also, the dungeon environments still look much better than in computer versions of Wizardry 1-5, and are still more varied than Wizardry 6's brick walls everywhere.)

Green_Hilltop: I prefer the animated Wizardry 6 brick walls over this game's dungeons, they have more charm and look more real, versus the dimly lit, barely detailed corridors. I haven't played Wiz 1-5 yet, but I do like the visuals of the old games. :)
