Sphinx hasn't turned out too bad in my game. My culture is quite high and very much outpacing my research. I normally like to research sanitation before getting universal suffrage, but it ain't happening this game. I was only like 12 turns for universal suffrage anyways without the boost (on epic speed). I should have stayed with King difficulty, as my game has been quite easy, and not a single person has declared war on me (though because of alliances I did have Nubia from another continent declare on me just recently). Playing with barbarians on is like easy level. Barbs put a hurt on Spain early on, though Spain later broke out and put the hurt on Korea and a little bit on Zulu (just 1 city). Mongolia was doing fairly well on the other continent, but I just recently passed him in score. I did build 1 of my UU for the era score, but never really used it. I only conquered 1 free city (Georgia's capital was flipped by Korean pressure mostly)
I'm not sure how you guys make your tiers. I've never officially made my tiers. I'll just go with the grade school system of A, B, C, D, and F. I gave last week's civ an A-. I'm nearing the end of my game already as its been pretty quick. I spent some time with my mom for mother's day, but I will try to get close to finishing today. Peaceful games with no wars can be quick. And my peaceful games mean no declarations of war and no conquering of AI cities (though I did conquer 1 free city, it was stable loyalty and wasn't going anywhere). As for my score, right now I'm leaning towards a solid middle C. Culture and Gold are pretty high with this civ which helps redeem them.
I still didn't put that many Sphinx's, but probably more than past games. Perhaps I underestimated them in the past. In the past I was reluctant to use unique improvements because they don't increase food or production, and almost seem like a drain. But at least with Egypt you can put them on flood plains and still be increasing your food and population with them. The game recommends I put them on desert squares, but I'd rather not. The exception is my desert square next to Kilamanjaro. I still don't have optimum placement of Sphinx's in this game. I don't like to micro stuff like that. I just throw them wherever.
And what do people think about Egypt's power level? They seem weak to me.
See my above paragraph. Before I would have ranked them lower. But they seem slightly stronger in rise and fall since it's a little easier to get into alliances if you are peaceful which means good trade routes. Commercial hubs are slightly easier to build as well due to production bonus of 15%, too bad that doesn't apply to district buildings though. Culture and Gold (and a little bit of faith) help redeem them. Much better than a civ like Georgia which only gives faith (and some envoys if you go through the work of converting city states). I'm ranking them a C. In the past I would have ranked them a D. But I had a lot of rivers in my current game which certainly helps things. Without rivers I'd rank them an F. They are nearly completely dependent on rivers to excel.
I _hate_ floodplains - so many cities ruined by that one floodplain in the middle of the jungle I didn't see until I tried to build on it
I'm finding flood plains a good place to put sphinx on as it is more than self sustaining. 3 food plus the culture and faith isn't bad. In hindsight I might have chosen the Pantheon to boost production, but my capital wasn't on flood plains, it was only later I had a lot of flood plains in my cities.
Screenshot of my current status. If anyone is playing the save I put above, feel free to share. It's always interesting how people develop their civs differently when starting from the same starting point. I could have went on the offensive, but that would have made things too easy. This is all peaceful expansion. I had no culture flips, though I did take the Georgian capital only after it became a free city (free city units still harass me even after the patch).
Yes I'm saving up gold in preparation for Big Ben. This is my favorite hobby.
One time I made over 50,000 gold from Big Ben.
