Ethiopia seems pretty good at first glance! Not as obviously broken as Gran Colombia, but seems in the upper-half of the cast compared to Lady Six-Sky.
AKSUMITE LEGACY: I do love getting bonuses from playing the game normally, and Aksumite Legacy fits nicely into that archetype. Extra Faith in the early game means a super quick pantheon; depending on your start, you're probably not going to beat Mali or Indonesia to it, but you could be on par with Russia's quick pantheon. Extra Faith from international trade routes is good, but not incredible, since in the early game you're going to focus mainly on internal trade routes. But given Ethiopia's Culture-through-Faith design, that synergizes nicely with needing Faith to buy Archeologists, Naturalists, and Rock Bands. And since that Faith is added directly to cities, that also works great with...
COUNCIL OF MINISTERS: So to lay this out on the table, this isn't necessarily an insane infusion of Science and Culture. Looking at Ethiopia's capital at 0:26 in the video, they've got about 8.5 of each from that faith yield. But hey, it's still free Science and Culture, which you might need if you're going to prioritize Holy Sites early on as Ethiopia. So any extra bonus to those yields in any Civ, especially a Religious one, is really good. And if you stack on a toned down amount of faith from five other Cities, that's a really nice amount of Science and Culture empire-wide. It reminds me a lot of Righteousness of the Faith, except you have to put in a little extra work to get that faith going. It will probably be better than RotF early on, but isn't going to scale as well. This is a very nice ability.
OROMO CAVALRY: Coursers are good, so a better Courser by association is also good. Extra Combat Strength is nice, but the extra sight sounds really, really handy to have on a super-mobile unit. On top of that, hills are usually the thing that hamstrings Mounted units a bit, so having a Mounted unit that is as fast on hills as in flat-land is super good. This is quite a strong unique unit.
ROCK-HEWN CHURCH: This obviously gives you a lot of Faith, which is really good considering that you also have Council of Ministers to translate that Faith into Science and Culture as well. Its extra Faith from mountains and hills also means you're going to inclined to build this in places where you'd like to build Holy Sites, which means Ethiopia can sort of build extra Holy Sites within a city, which is pretty neat. The asterisk to this improvement, however, is that this improvement will conflict with where you'd like to build Mines, which means you have to make a decision between Production and Faith. However, this is probably reconcilable in-game, and shouldn't take away from how much faith this improvement can generate. Oh, and they give free Tourism at Flight, probably tied to how much Faith they generate. Which should make Ethiopia
even better at Culture victories.
Obviously a heavy gearing towards Religion and Faith, so they'll be quite good at Religious Victories. What I'm really thinking Ethiopia will be good at, however, is Culture Victories. They're like a mix of the Khmer, Mali, and the Mapuche, in that Ethiopia gets a lot of Faith super early and benefits a lot from Trade Routes like Mali, have a unique route to translate Religious gameplay into a Culture win like the Khmer, and have a unique improvement that's tied closely to mountains that will pay off big dividends in the late-game Culture race like the Mapuche. This is probably my favorite Civ in the NFP so far, and I'd estimate them to be either high B-Tier or low A-Tier on first glance.
Tamar: "Who are you?"
Menelik II: "I'm you but stronger."
Oof. Well, if it's any consolation, Tamar's still really good at a Diplomatic Victory!.. But other than that, yeah their niche has kinda been overshadowed a lot by Ethiopia. Hoping for significant buffs or a rework come next patch.
