I like the new map, but it’s kinda funny how its the opposite of what I have been hoping for: Map variations or a big open map for better replayability.
I think maybe they made a simple short line map partly to test putting out content faster?
My suggestion for FS would be to take this new linear train map and make variations of it. The train cars are modular. Make lots more train cars. Make many copies of this new map with a random selection of train cars in different orders. Randomly load one of these copies when you pick the train mission.
Result: Linear train mission becomes one of the most replayable missions in the game.
