The impression I get so far: Game opening needs a kick that competes with quecha (Imp, combined rex/conquest?) First half of the game as always eco traits (Fin/Org/Phi/Ind) are preferred to reach Sushi/Kremlin fast. Second half of the game happy/health traits (Exp/Cha) are preferred to boost pop, assuming Future tech are likely to come into play too late to stay away from happy/health problems. All other traits are more or less obsolete now anyhow. Looking into score calculation (huge/marathon, ± T400 win date, >20k pop): => Every turn delay of victory needs to be offset by ± 0,65% pop increase to prevent score going down. At >20k pop that means >130 popgrowth per turn (500 cities, a city needs to grow every 4 turns) So later win date with higher pop from happy/health traits or earlier win date with lower pop from eco techs? I think the eco's win. (or is this too much simplified?) So IMO the best leader would be one with eco traits and a good game opener. I keep circling back to Darius, eco+immortal (starts with both AH pre-techs), potentially 6F health boosting UB. How unfortunate is a scout start if you could pop more huts? Should get you a tech more easy, maybe a warrior on the side....... The army would need to chopped rather than slaved probably. But since you don't need to build so much compaired to space game, that should be fine? Conquest on huge needs to be done with mounted.......... Almost all Imp (and Phi) leaders (notably not Suleiman) have poor starting techs which kinda spoils a possible jump start, no quick granaries fe. An optimal seafood start with Romans/Joao/Vicky will still not beat Gold/Gems at the start in a more central location. With max opponents on huge, are civ's placed on the map in pairs like on large? You would have a guaranteed war victim and not just need to rely on peace rex. As for Temperate/Tropical/Arid/Rocky/Cold => Only Cold maps have significant lower popmax. All others are the same. So Rocky/Cold/Arid are probably the ones you don't want. Rocky has been mentioned, AI hillcities and such. Cold will just make everything go slower. Arid contains increased floodplains that offset desert, thus overall increased unhealthy. I think Tropical jungle counts as 1F and has therefore the biggest potential to raise foodlevel, but is also a huge job to cut.
