So many answers, nice
Did you have a vassal there?
I didn't have a vassal in any of my non-incan games. In that game, it even developed more strangely. In one turn, they all suddenly were willing to trade their techs, next turn, WFYABTA again. This happened at least 3 times, and made absolute no sense to me. Also, Mansa wasn't willing to trade techs, and one shouldn't become a WFYABTA from him at any time if I understand him right.
A hated vassal teamed with the human player lowers your actual diplo stance, which brings back WFYABTA. But if the said vassal is also friendly as you are with a certain leader, then the effect is unnoticed.
Early vassals are usually not recommendable, but later when rolling one AI after the other, it
is nice to keep them healthy to let them tech for us.
I know that about the combined diplo-stance, but it was not the case in that game. Also: An early Vassal imho is the best you can get, the opposite of not recommendable. The earlier you get a Vassal, the earlier you have AIs bonuses working for you. Having someone that can research Guilds + Banks while you aim for Lib with a direct follow up of Eco is awesome. I was never able to get a Vassal that early though.
What do you mean by modern warfare? Rifles era, infantry, tanks and bombers? You don't need a tech lead to war in those eras, you just have to be smarter than the AI. And production with even tech is often better than a tech lead anyway. If you want a really fast war settle all the island, grow them, grab tanks and bombers and blitz the hell out of the other civs to reach domination limits. I don't know if this is too late for you, but I doubt it, you were pretty close to combustion, radio, industrialism in your inca game when you finished and Rome is a little slower.
I cannot answer this question right now. I will take your advice in my current game and post screenshots and ask for your help again. The biggest problem is just inexperience, being smarter than the AI should normally be no problem, I usually win my wars with only 1/3 of the units the AI has only by smart movement and good use of promotions and well combined forces.
Maybe you all can help me already in my current game, as it seems to be the best till now: This is from 500 BC:
The Scoreboard:
This is the one that looks really good. I'm number 1, though I don't know why, and have a decent number of cities. HC is as good as dead.
Demographics:
These are more realistic than the scoreboard. I'm only in the middle field of Gold, Production and Food, and even though all Civs were in constant war, and though I didn't do much but produce units, I'm last in military. I got the most land, but my cities are small, compared to the ones of the AI.
The land:
This is a big Screen, that's why it's wrapped in Spoilers:
This screen shows a lot. My neighbours are Pericles, who beat me to Lib and is tech-leader, Hatty with whom I'm friendly, Mansa and Lizzy with small Borders, and Frederick as another neighbour with large Borders. I'm trying to be the first to Economics, that's why all my cities are building research. Even with that though, I only have a research-rate of 350 BPT, I know from Pericles that he's got about 500 and Mansa has about 450. I don't have any espionage, because I don't have Courthouses yet, anyhow, my Gold looks quite ok, because I chose all the Gold-builders as opponents and can usually get some by techtrade.
I hope I can get the Beakers up by using REP and Specialists, I just conquered the Mids, but I need some Infrastructure for the Specialists-slots. I have a decent sized Capital that puts out most of the Beakers, all other cities are Mines + Farms production cities, I wasn't able to set up a real GP Farm till now, but will take the conquered Macchu Picchu for that because it has the HGs and I need some GEs for Mining Inc, Wallstree, Kremlin, etc.
On the map in the lower right, you can see, that the islands haven't been settled yet, as Astronomy is needed for that. Pericles took that by Lib, and will get even more powerful through that, I have no idea how to get it from him, as I got nothing I could trade for it, time to look at:
The Tech-Screen:
The problem in all my non-Incan games. Either they're on par with a slight lead, or they're totally backwards. My main goal is to get Astronomy somehow next, because I need to settle those islands for the Seafood, maybe I can trade it for Economics with Hatty, Ramesses, Asoka or Mansa somehow, though it will be difficult.
I think these are the imporants screens giving all the valuable information. It has to be said on plus, that all my cities have about 150 turns of whipping anger, so building an army now to conquer Pericles or Frederick seems impossible. I still got 15 Praets and some Siege from the war against HC though, but I don't think that'll be enough to fight, it barely enough to get a MP in all of my cities, which have been uprotected for a millenium.
Goals: Reach Sushi and Mining Inc, settle those Islands, but also: Conquer Frederick or Pericles to get a Vassal. Get research up while also getting the necessary infrastructure needed for Sushi. Get up a real GP Farm to start farming GPs and run some GAs (I also conquered the MoM already) . Further than that, I don't know, maybe you will.
Looking for a nice "normal leader" for early wars, I'd look into the Charismatic leaders.
Any decently promoted unit can mimic a UU (maybe not to this point but... that CR3 sword must be a good unit). Cha helps, there.
Napoleon comes fast to my mind. Very well-rounded leader.
Cha and Org is the combo that gives the most passive benefits (maintenance & happy departments).
France also has excellent starting techs and cool but discrete Uniques.
Mehmed & Hannibal & the Cha/Exp American leader also have this very "normal leader" feel to me.
That leads me again to Hannibal. He's CHA, his Numidians even get extra flanking for free, and he's also FIN. I don't know if they can compare to Rome though. Rome's Praets have no problems slaying Longbows, and I wonder, if any other unit could do that trick, even with extra promotions. It's just sheer base-str that seems to count most. Maybe I'll give Ragnar another chance, his UU seems to come just in the right moment where my empire is usually set up with Granaries and Barracks and 10% city attack and free Combat 1 don't sound too bad, and, it's a STR 8 unit.
I don't care about starting techs, as one always can cook the start to fit the leader, and because I get all techs with Oracle in 2200 BC so early.
I have to admit to liking Boudica and G3 Gallic Warriors, 50% withdrawls and the removal of the natural hill defense (from G3 hill attack). With Copper+Iron being useable, alot of starts can be used, thou with only the minor eco boost of +1

, 2 if spare hammers.
Guerilla is an awesome promotion, one can use the movement on the hills to attack faster while having a good defensive stance onesself. I think I will set her on my list for "leaders I have to try out" , I'm sure that "playing with Boudica is a lot of fun"
