ooo...Thalans with farms...brutal. Question...once you had this farm tech, were you able to research the other farm techs yourself? Or do you have to trade for them as well?

Same here...I've tried a couple with No Tech Brokering and enjoyed the change...though in the long run, I have a feeling I'm going to play mostly with Tech Trade off. Still, its been great fun seeing the races in the trade screen, even encouraged me to make up some custom civs using the Formis packs. Damn he did an awesome job...Formis = Legend.

10 to 8 (TA initial colony) is 11.8% difference-population is square rooted before it's factored into your income formula.

Maybe it would have been better if I'd said taxation formula, then.

You'll have to bear with me; I'm less likely to edit and correct posts than normal because of how slow page loads are over the 1.5KB/s "proxy" (Tunnel) I'm using to circumvent Sprint's madness (THIS IS SPARTA) regarding Cogent.

While it's true that you'll also have an increase to your tourism income, it won't be sufficient for it to bring that 11.8% up to 25%.  My guess would be 16% at most.  As a note, no one to my knowledge has done a population-->tourism formula yet.

Which gives me something else to test.
