It's been forever since I read about this but the map itself was generated randomly. It was then manicured by hand. The buildings and cities and dungeons were all hand made, yes. But the dungeons were all using such similar art assets and there was a real lack of variety, so they all rather felt the same. Not that I'm complaining, it was an amazing game and probably one of my favorite gaming experiences of my life. It was way ahead of its time.
