I think a lot of the computer game community don't like these, I see comments about them "not being games" because they don't have any guns or you don't collect coins, but they're both narrative driven adventures where you wonder around beautiful scenery at a walking pace.
The Long Dark is a survival game that's about making it in the frozen Canadian wilderness. I only gave that one a quick try but it looks promising.
