Expect Irony.
The barbarian functions as a 32nd Civ in the game, but without the cultural unity to found cities and develop technology, and no central leader.
What if the barbs had their own research pool, a small number added to it each turn per settlement on the map.
When the number adds up to a certain amount (average approx every 40 or 50 turns) one barbarian settlement somewhere in the world (determined at random) becomes a full-fledged Civ (using one of the unused Civs -- if all are used, it doesn't happen.) Then the barb research pool drops back to zero again.
The new civ starts at a tech level determined by the units the barbs are using at the time (Warriors, Horsemen etc...)
This is a way that new civs could be injected into the game after the start.
