#17 Dark Souls
The entirety of Dark Souls takes place in a relentlessly hostile environment called Lordran, the land of ancient lords. In what appears to be a twist of the typical adventuring trope, you play the role of an Undead. Your quest to ring the two Bells of Awakening and undo your curse will see you fighting unforgiving foes who will do anything to get in your way and prevent you from fulfilling your mission.
Quests aside, Dark Souls' medieval environment may be large and spacious, but you'll have some difficulty admiring the architecture and the scenery because just about everything in the world wants to kill you—and it's never a good idea to stay in one place for too long.
