I'm always looking for ways to make the geoscape more interesting... I have another idea that I'd like to hear your opinions about.
If you transfer stuff from one base to another, how about there's an actual transport craft that you can see on the geoscape? I don't suggest that you have to use one of your own transports, it could always be a rent-a-plane from friendly military.
it would actually fly on the geoscape as a radar dot just like one of your own craft would (perhaps a different color). aside from being a visual cue as to how long the stuff actually takes to arrive at the other base, this could spawn missions of its own:
- the craft might be attacked by a UFO (so you might think about sending one or two escorts for that transfer order of 2000 units of elerium).
- if it is shot down, it would spawn a new kind of mission: a landed ufo next to a shot-down transport craft. if you go there, it's search-and-rescue.
- it might even discover a UFO by chance (small radar range and low detection chance, but still)
