A few notes:

*As Micah says, late era strength is rather arbitrary, it almost always comes down to how well the nations have done in the earlier stags, not theoretical late game nation power.

*Ease of learning is also a bit arbitrary, some nations are cakewalk if you know basic bless tacics, but extremely challenging otherwise.

*I assumed nation power relative to other nations in their era.

*I was extremely tempted to put 6 in for some categories with LA Ermor/Ryleh, because as it is, it implies some otherwise powerful nations would be a one on one match for them.

*I consider early game approximately pre-level 4 research.
