I was wondering what people thought about no tech trading in Civ 5? I know there are research agreements, which is a cool idea...but tech trading is out. Seems to me like no tech trading would be an interesting idea. I know it was always an option in Civ 4, but having research agreements instead seems pretty sweet. If there really isn't any tech trading, I think things will change quite a bit, particularly on higher difficulty levels, for people who are used to researching uncommon techs and trading them with all AI civs. Pretty cool!
