Well if we want to move to Diplomacy, I can get the expansion, so I'd be cool with that. Just don't want to manage two versions. xD Though, I have absolutely no idea how the diplomatic techs work, and perhaps more importantly, how to get rid/manage the silly "races" stuff. But yeah, I could always temporarily do away with the diplomatic tree entirely, assuming it doesn't break the game. Or put in 2-3 "filler" techs that cost nothing and take 0.01 seconds to research, until things are ready to be done in terms of that tree.
