How about using procedural stuff to add perhaps one new route per month?

[Stewie Mazen]

Procedural stuff works best if your project has rules.

Oh look, its a project where people drive trains on rails on planet earth. I heard making a railway route is rules only. How convinient.

1. More content per year than replicating RL.

2. More 😧

Two ways how to enter the phantasia land: There will be depots you can go in and come out in non-rl-map. The new map is either like the current one huge or split up in loading screens.

 

But yeah I really believe that railways are perfect match with procedurality.

Procedurality is a lot harder if your map needs to fill up something like the RD2 game.

But here everything is on rails and few meters next to it. So much more doable.
