you know, there is a rather simple way to turn this lame 'science and culture from trade routes' ability into a really good one, and that is to give Russia bonus great people points from trade. First, of all aspect of the game, the gp one seems like the most fitting to Russia from the historical perspective. Further, it also fits into the leader ability or at least the same ballpark: there were some scientists from Europe working in Russia in the 18-19th centuries. I suppose it is an easy and also much needed tweak.
