I would like something halfway between Snowrunner and European Truck Simulator, with a well written single player RPG story mode where you get to help people by delivering stuff.
Or, something like Breath of the Wild only without fighting.
Or both.
I'd like to try it, but I don't have a supported device yet ... I've played at least one indie game with a similar feel and really enjoyed it, but it was short and simple so I didn't get lost in the world
