so get it while you can
Example: If you bought the HHR route for Train Sim World 2, clicking on the “install game” button on Steam for the TSW5 free starter pack (no, you don’t have to install it) will automatically give you the TSW5 version of the HHR route with no further steps; if you’re on PlayStation, you do need to do the same process for TSW4 first.
You don’t even need to buy it, you just get the free TSW5 starter pack
I’ve seen some reviews say the free starter kit is only for a limited time. Dunno if that’s true but this is the first time they’re doing it so I’m not taking chances.
