Hmmm choices. Spoiler 1470ad : Which lib tech to take. Short term I need frigates. Communism would be great. Would reduce costs across entire empire. Not quite ready for mass workshops. Free great spy and lots of techs to steal. His caravels are a pain. Physics is a 6550 tech but gets me airships and a free GS. Albeit GS bulbing is limited. I am getting just over 2000 beakers from bulbing. Still missing a lot of basic techs here. Pretty sure Zara has about 10+ techs I need. He will certainly be building a fleet here. For now I don't want to meet any more AI. Chances are they will be backward as 1470ad and lib has not been taken.
