The scale of this game and the fact that basically everything outside of story dungeons and certain locations is randomly generated for each playthrough is absolutely insane, but that leads to a lot of weird dungeon layouts. It feels more Elder Scrollsy than Arena did with more books, a bunch of different factions that have relationships with each other (even if they basically all serve the same purpose as randomized quest givers) and retroactively being one of the weirdest games in the series narratively thanks to its Numidium-powered reality warping shenanigans. Sometimes the dungeons can be downright noneuclidian in their design, but overall a fun time and easier to get into than Arena. I would recommend checking out Daggerfall Unity instead of trying to play the original through DOSBox, though.
