I’ve been playing euro truck simulator 2 and I was like damn I wish there was a Japanese truck simulator that would be awesome, well turns out some fans in Japan have been working on project Japan, a mod that replaces the world map with Japan!! You can also add any radio station you want to the game if it’s in the right stream format so I added a bunch of Japanese radio stations, I also later realized I can change the in game currency to yen so: I’ve been playing Japanese Truck Simulator today
I'm having trouble finding even more decked out examples but yes
