O’Connor’s review of the tourism Quake
I don't think Quake is suitable as a game used for shooter --> walker comparison. It is very old and the graphics reflect that. Nowadays, shooters probably have more complex environments than old-school walkers. The limitations of the technology at the time shouldn't be an indication of how well a shooter could be transformed into a walker today, especially as the game development and modding community has exploded.
While walking, as an act in and of itself rather than a means to a practical end, has long been demonized as an inefficient form of travel or a wasteful pursuit of the privileged,
I wouldn't say walking has been demonized, but rather that new forms of transportation in gaming attracts more attention. In gaming, you would probably prefer driving a car or riding a horse, things that might be unavailable to you in real life, instead of walking, which we do all the time. In opposition to this, walking simulators enhance the focus on the environment and other mechanics they have to offer, rather than exciting movement.

Showing the POVs of all actors can evoke sympathy from the reader.
Suspense, fear of abandonment, fear of lurking attackers, and fear of loss of self
Sources of anxiety
in stories that are goal driven enough to guide navigation but open-ended enough to allow free exploration
Perfect in-between for a participatory narrative form.
