I think this game should have Sattelite Communications so it gives limitation compared to a manned mission. There should be 2 types

Communication, these are for ensuring other sattelites that they can have connection to the space center These are more cheaper than the other type.

Direct, this would be a type that cannot connect to other Direct unless there is a communication sattelite able to connect to it through wifi. This would have a better range than communication and cheaper to give this more importance because in ksp, the direct ones aren't that useful.
