I wonder if there is a limit for the population of tribes.
I strongly doubt that any tribe large enough to actually control a significant area on the server will be able to maintain cohesiveness. The biggest corporation in EVE that I can recall was EVE University, a training corp, and I do not believe their membership ever exceeded 2000 players, with an active playerbase of 200,000+ Alliances on the other hand got rather larger at times, but they are not single political units.
Sure Xsyon is not EVE, but they are both Sandbox, and share a lot of game dynamics, even if the background for said dynamics is drastically different.
