Has anyone ever tried to give a freights to an AI so that it would then begin a trade route with one of your planets? Does ity work? will the AI send the ship somewhere? This could be a good way to exceed your max number of routes and if you give it whiles its in the heart of your territory, the risk of it going to another civ is lessened.
IF the answers are YES, then how does the game cal;culate the value of the route? WHere will it say the route stated?
Also since you benefit from the route too, you can get better relations with the gift and then get money from the route.
