The base game only offers a limited amount of scenarios, and not very many. Once you play the sim for a few weeks, you've most likely completed every task. It would be nice to allow for scenario creation from folks like RBJets or High Iron Simulations, to add many more countless hours of additional fun.
they could even use the system from TS2020 with the marketplace to sell scenariopacks if they rather not have the editing system public,I wouldn't mind at this point,running out of things to do,longer routes would also help,can't see how they'd make scenarios if they plan on releasing high speed trains on a 30km track
