Lets see if I can work this out,
The way I see it you'd have to have to seperate 'dimesions', the one with the planets bases etc, and hyperspace, have them overlap in such a way that when you enter a jump hole (or hyperspace gate) you enter into hyperspace and can travel to any destination you want? If thats the case I recommend making it significantly more hazardous to travel long distances (e.g. Hyperspace is radioactive and the longer you stay in there the more damaged you become) to prevent people going to one side of the map to the other in a short distance of time. But on the other hand much faster transit between one side of the galaxy to the other would be good as it would speed up the space of the game. Either way, looking forward to it RE your a hero to us all
(oh yeah and If I'm wrong feel free to slap me
