I feel like the end game items need some more complexity. For example for low density structures you could have aluminum instead of copper and add some new chemical from a more complicated oil processing system.
Rocket fuel could also do with some extra fluid to make it more of a step up from solid fuel
Unfortunately they recently went the opposite way and dumbed down oil processing. So I doubt anything like that will ever happen. They rather want a more streamlined game
Easy to do. Just read a rail signal and if it's red you know that a train is there* Soooooo many train deaths, any chance of rail-crossing signals?
The colors by themselves don't mean anything. They are just there to differentiate the rail segmentsThe signal placement UI needs a legend to say what the different colored lines mean
Try the rocket launcher. You need lots of ammo, but they have quite some rangebecause its hard to get the range on big spitters
