Games with destructible environments
Games With Destructible Environments on Steam start with People Playground, Teardown.
The terrain or architecture can be removed, carved, or collapsed. Space itself is a resource you spend. A wall is only a suggestion until someone decides it is a door, a trap, or a hole they will still remember next session tonight.

How destructible environments changes a game
Players remember holes they dug more than rooms they were handed. Trailers sell the moment a wall stops being a wall, which is why Teardown and 7 Days to Die clip as demolition. The pool here is tiny on purpose — two listed titles do not licence inventing a third. A destructible crate in an authored shooter does not qualify; the map itself has to be the inventory.
