Does anybody else desperately long for an option to turn off tech trading? I think that trading technologies is far too abused, both by AIs and humans. The (most or even only?) successful strategy of putting 100% income to gold and buy/trade all your techs on difficult levels, is in my opinion somewhat like cheating. It also takes away half the fun and meaning of the game. How hard can it be for Firaxis to include a rule option in the start up screen where you can turn that off? I have tried to mail this suggestion to them, but without response. I mean, it should at least be POSSIBLE to play a successful science game on emperor/deity.
