Nope. Your nation becomes different once you start taking cards. Other games do this, but it's not been done in TTA. Not sure it would work, but maybe.
I feel like part of what makes TTA so wonderful is how quickly and meaningfully nations become asymmetric just by playing the game.
Nations don't feel vanilla and samey after like turn 3. They feel like the nation that built the Colossus under the leadership of Hammurabi very quickly.
