Distinct civ abilities should appear during the game depending on the way so. is playing.
The tech tree should have many more unnecessary death ends that aren't required for further development. That should be implemented so that one will pick out only the ones that he needs for his strategy, because otherwise he would fall behind in the main technology tree. So civ specific abilities would appear during the game. E. g. a Knight with upgraded armour and weapons, best training and morale shouldn't be as efficient as a regular cavalry with rifles.
Then there should be no more unique World Wonders but only national (small) wonders. The idea is the same like that with the tech tree, that one will build only the ones he actually needs for his strategy, Building most of them would result in neglecting the infrastructure of his cities. Every national (small) wonder should lose its effect later on.
At the same time these extra efforts in tech research and national (small) wonders should be classified (in categories like military, government, education, comerce, science, religion, agriculture, industry, etc.) and as a reward, the nation should get a bonus for future efforts of the same kind.
