I don't play simulation titles for their gaming.. progression.. if you will, so I'm wondering if there's a way to just cheat all the collectibles and mastery rewards. I do like how they look when driving a route.
For collectibles, on PC you can either for example increase the max running speed with a console command (ts2.dbg.MaxRunSpeed) and run through the route looking for them, or teleport to each of them (ts2.dbg.JumpToLatLong) if you know their world coordinates.
