As somebody has already mentioned before, in High Earth Likeness (on a huge map), Russia spawns too close to China, so that there is no space for Mongolians between them.
In fact, in my first (and so far, only) game, Russia spawned right next to China, but there was a big gap to the west between Russia and Germany. This kind of makes Russia into an Asian power, rather than a European one, so the UHV condition can only be met by colonizing to the west, which is problematic because "Europe" is jam-packed with civs.
Also because there was no space left on Asian mainland for Mongolia, it spawned on an island (or maybe it was a big long peninsula) next to Japan!
So I would really prefer for Russia to be moved further west, at least for High likeness.
I have seen this many times as well, and think that Russia should be more of a European than Asian civ.
