DiRT Showdown then morphed things into a destruction derby-athon, the success (or lack of success) of that game causing a bit of an identity crisis leading to the hardcore rally sim of DiRT Rally, but then that was followed by DiRT 4s impressive procedurally generated rally stages, and now we have DIRT 5 (now with a capital i) and its Playgrounds mode.
