I try to play the tech trader as much as possible on Diety level. It is really annoying how the one or more AI Civs can clearly not have a tech that I just traded another CIV for at a high price. Then when I go back to sell it to them they magically have already. I even offer nice gifts as a way of checking to see what techs they have before looking for a possible trade with other civs. This would not be a big deal if it happened once in a while but multiple Civs are getting away with this almost every time I try to trade. What can be done? I read some where before that this was caused by loading an autosaved game....which I never do so I don't think that is it. Anyway....I know it is possible to make huge sums of $$$ by trading and I am already making about $800/turn right now...but The AI already gets HUGE advantages on Diety level. This to me does not seem fair. Plus..I am basically giving them free techs just by trading with another Civ. Oh well it is starting to sound like a rant and that is not my intention. CAN'T WAIT FOR THE PATCH!!!
