I really like the idea of havin a red circel on the map with a radius of 250km arround the KSC.
Outside that circle the "Recover Vessel" option (both in flight and trackingstation) is disabled.
The circle marks the 0% funds for recovery mark and the ksc is 100% with a let's say 20km radius as a bonus to compensate the lack of recovery outside of 250km.
Would make the game interresting at least and stil be fair because of the better payment close to the KSC.
Just an idea I had.
Cheers.
