I know this is a bit of an odd request, but I'm looking for a game or a sim where you can drive vast swaths of land in the countryside. Cities, towns, and villages are optional. I'd like it to be in a first-person perspective, and preferably on PC. I don't need for it to contain or to be about racing. I require it to be offline, or at least have a fully-functional offline component with the aforementioned country driving.
Imagine what I'm looking for as more of a virtual road trip with lots of enjoyment of the sights along scenic routes and byways instead of a game. Also there should be the option to go off-roading whenever you want. I would be happy if the game/sim contained both elements of casual driving as well as racing for when I'm feeling adventurous, though. The game's release date can be from any decade.
Could anyone please name a game with these requirements? Or even better, do you have a sim/game worth recommending of this type?
