Have started a game on difficulty emperor and from my earlier experience the on Regent the AI has kicked up a notch. Even though i thought i got a pretty good start and manage to get 2 techs from huts the AI non the less outran me in techs after awhile trying to keep up with high science slider i decided instead going for a lone scientist and buying/taking what i want instead. Did a bit of mobilization and manage to gather enough immortals to crush portugals spearman defence. (Even though he finnished the great wall 2 turns before i started my invasion). The main reason for me starting this war was to catch up in techs as it were to expensive to buy everything from the other civs. Portugal first offer currency for peace after i took Lagos and (razed due to 1 pop) another city, but as I thought i wanted more of the 6 techs they were ahead of me and that I could easily take their capital made me refuse the offer. Now i have just taking their Capital for the second time. Proposing and see what they might offer for peace this time. And manage to get 3 techs at least. Currency, Code of Laws and litterature. But is this really all could get? Does I have to wait until 20 turns runs out. Make a new strike and then demand the rest? Or is some way to squeeze out all their techs now? At this time i don't want to hurt my reputation so i guessing to brake this 20 turns peace agreements also will be very bad for me. Posting a save so can you see the situation for yourself.
