Sorry, I meant victory in 1685, not 1865.
And is there a rule about minimum turns to get some techs? Sometimes it seems even though I have the science output to get something in only a few turns sometimes the game caps me so that no matter how much I increase my science rate my gold per turn goes down but my turns per science doesn't. Is there a minimum and/or maximum turns for each tech instituted to try to keep your tech close to that which is appropriate for the calendar year?
