Not much to report for the time being. I think there are some issues with Russia's starting techs and units (I definitely think AI Russia is doing poorly right now as well), but I don't want to say much yet. Much of Russia's UHV is backloaded, so it's not really possible to judge how well it's going yet.Excited to see the "Leoreth plays Russia" thread
I don't think the barbarian spawns are that much trouble, they can be easily countered by Skirmish promoted Horse Archers, but I haven't encountered the Mongols yet.
Russia is definitely a case that would benefit a lot from the new map due to the new terrain types, which do a much better job at portraying the region correctly. I also think it would be a lot more interesting to have a Kievan state followed by a Muscovite state as different playable civilisations. It's strange that you don't have anything to do except building up your civilisation for the first couple of centuries.
