games that are nontrivially about walking/hiking

"If life itself, the passage of time allotted to us, is described as a journey, it’s most often imagined as a journey on foot, a pilgrim’s progress across the landscape of personal history. And often, when we imagine ourselves, we imagine ourselves walking; ‘when she walked the earth’ is one way to describe someone’s existence, her profession is her 'walk of life’ […] The metaphor of walking becomes literal again when we really walk. If life is a journey, then when we are actually journeying our lives have become tangible, with goals we can move toward, progress we can see, achievement we can understand, metaphors united with actions."
