Well isn't that the idea of an historical path after all?

Historical path means to me, that I can anticipate how certain Civs develop going forward. If I want to play against America in the Modern Age, I'd like to know, what kind of Civs I have to select initially, to end up there (that's how I would like it to work at least).
For me, the amount of the Civs is among the least of my concerns and I also sort of expected this. Solely because of the Agenda System (which is completly unnecessary in my opinion) which makes setting up a Civilization more complicated than in Civ 4 or Civ 5.
