I suggest to do more work on the matter of weather. Follwing points should be added at some point in TSW: Dynamic Weather: A great enhancer of realism would be weather that changes thourghout time. I know we have a somewhat dynamic system concerning heights (if you start at Chur in rain it's possible to have snow in Arosa), so some basics are there. If would be nice to then be able to set the sensibility of weather changes. Or the probability. The scripted dynamic weather like in the LGV scenario is very cool! Thunder/lightning: So in the TSW core there is already the functionality of that, see here: The thunder sounds spot on but as you can see by yourself the lightning looks like the development of that stopped mid way. So maybe continue with that, it hugely changes the atmosphere. Rainbow: Sunny day + rain + daynamic weather so the rain stops = railbow
