The idea is good indeed! Think about it: - career mode starts. Players choose the location where to build their Space Center. Equatorial positions are far more expensive. - at start players' KSC will have very few KSC buildings (maybe barracks style, to launch only some V2 style rockets), they will gain money and tech by performing missions in competition with other players (cooperation is always possible). Player syncronization is an issue here (maybe would be better, but much harder, to design AI players). - everything needs money; from fuel (fuel depot building at KSC?) to recovery of a landed craft (the farther from KSC the more expensive will be). Just some ideas running into my head. Bye!
