I was reading several threads today relating to leader traits and got to thinking that an interesting way to accentuate the differences between the traits whilst not introducing difficult to balance tweaks to low level game mechanics might be to extend trait advantages to research. What this would mean is that each trait would have an affinity with a particular set (maybe 5 or 6) of technologies...granting a discount when researching those technologies. This exists today in the form of the free starting technologies for each trait and would simply be extended to a number of additional key technologies that are clearly tied to that trait. To maintain balance and ensure the tech tree is not run too quickly this would probably require that the remainder of the techs get slightly more expensive and that the leaders be less inclined to trade away technologies that are linked to their trait. So...what does everyone think...vote away!
