Has tech cost been reduced since the last alpha?
Tried an Ottoman game and on spawn half the world was protestant (founded in late 12th century) with France and Germany popping all wonders with a massive point lead to the rabble.
Tried a German game after I saw the early AI's Printing Press and got it myself in 1203, by the time my third UHV completed (1560) I was starting on the Industrial Revolution tech
Same with a Dutch game, starts off being a whole era or more behind FRA/GER which makes Europe a rather dangerous place for a newcomer
England is only doable if you get a French stack in one of the flip cities (tried 5 times

), but a long .. oh so very long climb up the tech tree and not seeing any sort of parity unless FRA/GER suicides each other.
Austria are pathetic, again probably due to no longer having a tech buffer on spawn, used to be able to pimp Chivalry for a lot of the missing techs on spawn making the catch-up much faster. They vassalize to Poland of all things in most games.
Moscow never seems to get going, very slow expansion from what I have seen. Perhaps a little more southern aggression is in order so they can nab those tasty Kievan left overs.
Hungary and Bulgaria AI's are very competitive now (read: they don't collapse constantly), although they don't seem to have the grudge match going that they did in alpha releases, could just be me though.
Venice took a huge hit whatever was done to them. AI used to rule the Mediterranean with cities all over the smaller isles, now they barely make it to southern Greece. At least they are not uber-techers anymore .. much more on par with the rest (until Towns kick in in GER/FRA that is).
Norse are Norse. Can be powerhouses or whimpy little vassals, seems to be dependent on luck with RNG when they go pillaging ..
Isn't it possible to have a UHV other than raze an entire empire, very stereotyped considering what they gave Europe (Normans, spread of Christianity). I feel that something like building trading-posts in unlikely places is more appropriate.
Personally think that one of the reasons for the tech madness is the Free Peasantry/Limited Monarchy combo. On the vast European stretches of river grassland it just gives such an insane output ..
German game I cranked Line Infantry in 1.5 turns from a non-capital cottage farm, +300g/turn, 2k+ beaker/turn@100% .. just seems wrong
