I do not like this game at all, its not fun imo, but yet it's still admirable. It's a unique work of art created by one eccentric guy. There is zero compromise in it.
this is legitimately one of my favorite games. Moments that are relaxing, moments that make you feel truly accomplished, moments that are really really hysterical. Made me nostalgic for my days as a teenage dirtbag, and somehow nostalgic for a country I've never been to.
It has a ridiculously accurate simulation of a working car, through which I learned that I really enjoy working on mechanical stuff. I've moved on from the fake Datsun to working on real motorcycles and it rules.
