I promised it and here it is, my views on Crimea. I also just noticed: apparently I covered these civs in backwards order.
Royal Knight: This unit goes to the ”solid, but not exceptional”-category. Situational combat bonus on player’s own lands is not only when defending but also fighting enemy units after successful city capture. Receiving terrain defensive bonuses also lets player not only to hold their line better but also to be more aggressive with this unit since counter-attacks won’t hurt as bad.
Like I said, this unit isn’t anything special, but gets the job done reliably.
Greil Mercenary: Notable thing about this unit is it’s placement on the tech tree. Normally Swordsmen aren’t really used since they are not placed on the preferred Civil Service-Education tech path. By placing this unit on Currency, you have actually made it relevant for most players.
Best thing about this unit, however, is its unique role as a cheap unit for emergencies or quick wars. If this unit had to build, it would be competing with Pikeman for the role of primary front line soldier and (with its lower strength) would always lose. But since it’s buyable for cheap, it is basically Crimea-only Landsknecht that doesn’t require policies. Thanks to this easy accessibility, it can be used to fill possible holes in player’s army in a hurry. Also because it can leveled up so easily, player has more incentive to research Steel, upgrade his Mercenaries and keep using them.
I didn’t try it out yet, but I can see a strategy where player would research Currency as fast as possible and use this unit to quickly rush his neighbor. That could prove to be interesting.
Children of Wisdom: I have seen some people to criticize this trait and I unfortunately have to agree with them. This ability really unbalances the game, mainly because of how early and easily player has access to extra science by building farms.
Right now Crimea plays pretty much like a supercharged hybrid of Korea and Babylon. Just like Babylon has access to fast and easy science in the beginning of the game by discovering Writing and planting their scientist, Crimea gets (even more) free science just by doing what players would normally do, building farms. And just like Korea, whose “science from specialists” scales to later game, Crimea’s science output also grows naturally as the game goes on, only this growth starts much sooner and is much quicker.
This has dramatic effects to the game. In the early game, I easily doubled my normal science output. Even in later game, this ability multiplied my science roughly by 1,5. Because of this, I quickly took the tech lead and eventually had more than ten techs over the average amount, and fifteen more than the last AI. This in extension meant that my army was always more advanced than my opponents’, which made wars pretty unfair. I also had access to more advanced buildings which made also my economy stronger than my opponents. This, of course, included science buildings, which meant that my advantage just grew larger.
My fast tech progression also introduced problems for me. Since I was getting new buildings much faster than normal, my production couldn’t follow and I didn’t have time to build even half of the buildings or units I had access to. This made the game feel hectic and uncontrollable. This in turn made me frustrated and the game unfunny to play.
While I may have made this ability sound terrible for game balance, it is not fundamentally broken. It is thankfully pretty easy to fix.
1: Tie the science bonus to Education-tech or university and reduce it to 1.
The biggest problem with this ability right now is that it starts to snowball too early and too fast. Since any bonuses have biggest impact in the early game, the easiest way to lessen the impact of this ability is to postpone its activation. Discovery of Education seems like logical timing for this ability to activate: theme wise it makes sense and bonuses of this magnitude can still make noticeable impact to the game at this point.
It doesn’t really matter whether the bonus science is granted by simply discovering Education or by building universities. Whichever is easier to code could be used.
I also strongly recommend you to reduce the bonus science to 1 beaker per turn. While 2 beakers is fine for specialists who have to be supported by other citizens in the city, we have to remember that farms are self sufficient. There is also no clear limit how many farms city can work, but city can run only limited amount of specialists without sacrificing growth. Therefore working farms is not nearly as limiting as running specialists and any bonuses for farms can run out of control much easier.
I think the extra food from scientists could be retained in this ability. It isn’t really game breaking and is pretty unique bonus.
If you want to take this ability in new direction, I could have an idea:
2: Science buildings are built in half the usual time.
This bonus could be helpful at any point of the game, since science buildings are pretty much always pretty high on players’ priority list. It would also scale on its own to all stages of the game. And the scientists’ food bonus could be combined to this ability as well.
I wasn’t sure whether I should include this idea to this post: I think all change suggestions should follow author's original idea as closely as possible. In the end I decided it would not hurt to include it, maybe it at least gives you some new ideas.
Conclusion: Both UUs are solid and Greil Mercenaries give some interesting possibilities. UA needs some scaling down, however.
Well, that takes care of the beorc civs. Again, thanks for making them and good luck on your future projects.
science from every farm and + 1 
food from every scientist.
combat strength bonus when fighting in Crimean territory. It may also receive defensive bonuses, unlike the Knight it replaces.
culture. Great People heal units in the same tile, taking twice the damage healed 9thanks to ViceVirtuoso for the lua for this one! =)
faith from kills equal to the combat strength of the unit killed.
Thank you for all your civs and keep it up.
