Bottle
Bottle is an interesting walking simulator, to say the least. Find some goodies in the wilderness, but aside from that…it’s best to keep walking.
Walking Simulator
A walking simulator is exactly as the name suggests. It’s a game that involves a lot of walking, and walking, and some more walking.
These games are also called environmental narratives which is a nicer term.
They don’t JUST contain walking, although that’s the main portion of them, but a lot of walking sims allow you to look at pieces of the environment for backstory, or contain puzzles to progress.
Some examples of well-known walking simulators are:
What Remains of Edith Finch
Death Stranding
Firewatch
