Few experiences in any fantasy game compare to the thrill of stumbling across a dark, sprawling dungeon that leads deep underground, filled with secrets and rewards. Traditionally, many dungeons in fantasy or open-world RPGs are completely optional and easy to miss, making discovering a hidden, hours-long subterranean region a rare treat. Descending further into the darkness with only the light of a torch or a faint light from above can be a highlight for the player.
