First of all I'm going to list the uniques and stats of Persia and then I'm going to tell you what I dislike about the current version. UU - Immortal Replacement spearman +1 CS and double heal promotion compared to normal spearmen. This unit is fine, really, it isn't mind-blowing or anything and it got a lot worse with the healing-penalties added to CPP. But it is fine, keep the unit upgraded and you'll have meatshields that recover faster. EDIT: Turns out this isn't a lot worse with the healing penalties, since it doesn't actually double your healing as marketed, it increases your healing by 15 (or 10 can't remember) per turn. Pretty misleading however. UB - Satrap's Court Replacement courthouse Builable in all cities. + Merchant +1 gold +1 gold/5 citizen +1 happiness +5% GA duration. I'm not going to lie to you, this building is pretty great considering it pretty much replaces nothing, meaning all it's effects are things that other civs won't have access to. No, my problem with this building doesn't lie in its power at all, but more in the fact that it gives you +% GA duration an effect that normally (for a good reason) isn't included in buildings, mostly because it scales horribly with mapsize. the difference between a duel man where you can fit 3 (being generous) cities and a huge map (or just communitas) where you can fit 33 cities (at least) is a whopping 150% GA duration, translating to 15 extra turns of golden age on standard speed from a great artist. Yes I'm aware that expanding and building more cities is supposed to be the norm, and I don't question that at all, ofc building more cities should give you an advantage. But with this building is just extremely poorly balanced between mapsizes and maptypes. There are a few other ones working like this, mostly the Roman extra gold from city-connections per building thing (that really isn't a good idea either), and while it doesn't directly break the game I just don't see a reason to keep it like this. I mean Persia already have a big bonus to GA-duration in their UA, no real need to keep loading them up with even more GA duration. My suggestion would be scrapping the GA duration on the buildings and replacing it with some way of earning GAP, possibly just a basic per turn thing. I would personally love something that actually stays relevant as eras advances but that seem kinda unlikely. I would also like to go back to my initial point about how conquering civs could keep the Satrap's court in the city (not-razing mechanic) to symbolize how they were actually really effective ways of governance that was kept in place when the persian cities fell to invaders. Just a little bit of flavor kinda like the extra gold from plundering Egyptian burial tombs. UA - Achaemenid Legacy +50% GA duration +25% CS and +1 Movement during golden ages My complaint here is the same as always, I really don't like the combat focus of this UA. Persia did stuff other than just beating people up all the time. CEP had golden ages giving Persia extra culture, but I don't think that's a good solution either. Final note: I really don't like Firaxis choice of leader here, there are a lot of cooler Persian leader than Darius.
