After reading kjn's post I got a little inspired, so here is a pretty unconventional idea and some more run-of-the-mill ones. I'm not saying they are any good, but I think they could be fun to pull off:
1) Ragnar or Monty of Ethiopia. Get to gunpowder and nationalism and draft a fuckton of Oromos. With barracks and Theocracy you're looking at a possible Combat I / Pinch / Drill II draftee gunpowder unit. Monty will probably be best here to do 5-turn switches from economy civics and into nationhood/theocracy. Ragnar would be better at keeping the economy competetive though.
Either beeline steel for a Oromo/cannon offensive or beeline rifling and after a sufficient number of Oromos has been drafted/built then mass upgrade into highly promoted rifles and go on a rampage.
Unfortunately the Ethiopian starting techs aren't exactly mouthwatering.
2) Sitting Bull / Frederick of Spain / Sumeria. Build Great Wall and do an espionage economy. Frederick of Sumeria could get cheap courthouses and fast Gspys into play very early. However why would we wan't to be dependant on the other teams ability to tech, when we expect to be in the tech drivers seat ourselves?
3) Any-SPI-leader of a-good-or-solid-civ. I am 100% in agreement with "Locke"
when he praised spiritual as an awesome trait in PB4. It opens up a ton of possibilities in the mid and late game and with the amount of talent and MM obsession on board in this team, I have no doubt that we could milk this trait to its extremes.
I'm mostly just along for the ride here, as my skills in civ are nowhere near a lot of you guys (emperor SP player
), but regardless I thought would just give my 5c on the subject.
