1: Is the first town center the most important town center?
The first TC seems to be the only one that blocks enemies to build near your colony.

[(2):Units that get a stat boost from the TC trough various ways:
Haiti units and French foreign legionarre are units which get stronger the further they get from "an"* TC, while the Ethiopians have a unit which gets stronger the closer it gets.]

2:Is the first TC that gives this bonuses?
If yes: Does the destruction of the Main TC make the units above useless (Average for Haiti)?
Does that mean the civs like Haiti have to Protect their TC like a king in an regicide game?
Does that make the canadians the worst ally for Civs like Haiti since they have a shipment that gives 2 TC caravans at the cost of Reduced HP for all TC's?

If no: Which TC has the priority over who's giving the bonus? (For example, 3 TC's at 3 different distances, the further or the closest gives the bonus?)

3:Is this bonus acually tied to the spawn location of the player instead of the TC itself?

4:Why the Latin American Town halls seems to have a limit oh how far it can be build from "an" TC?
Does that mean the distruction of the TC will make this building unable to be obtained?
