I think that the movement times from orbit to atmosphere to city and vice versa are unrealistic. It doesn't take 2 hours (1+1) for a space shuttle to exit earth's atmosphere nowadays, let alone spaceships from the SW era.
Are these long times required for any balance thing? Does it serve gameplay in anyway?
I don't know if it's just me, but I would like to see this changed, if it isn't much of a programming problem.
This does not belong in the Problem Centre, since it is more of a game suggestion than something you are having trouble using (as such, closing this thread). However, it was implemented for a reason and it has been stated repeatedly in the past that the delay will not be removed - so I would imagine that it is indeed necessary.
