I was thinking the other night that if trade routes lasted as long as a traverse to and from target city then at least they could free up a bit faster. At the moment they are too long to really be strategic. Naturally you do not want to keep refreshing a short route so perhaps a notification the have finished and then the carry on by default but can be re-assigned, perhaps being displayed as such in the trade screen. I know it’s probably not what you want with faraway spice routes and the like but that would be quite a radical change? Anyways, their elapsed trade route algorithm is weird anyway with some shorter routes lasting longer that longer routes. UN is just an area I do not want to go to. Favour is way too traceable to be worth hogging for silly votes.
