Since buying the union rep didn’t pass, this is another idea for victory. Golden Routes are expensive, and not really useful at all. Its scouting cost of 15 is equivalent to Driving five Airport Routes in a row; or making good use of Repeat Routes.
As for the exact Victory Achievement condition, I thought maybe there could be a limited number of Golden Routes, and when they are all scout the Driver with the more Golden Routes wins, or when a Driver owns more than X Routes and has the more Golden Routes, or something like that.
Anyway this subrule doesn’t have much effect right now (except for rising the cost of random scouting, maybe, but this one was already too high in my opinion), so I see no reason why not to vote for it! :-)
