We got to remember that the Pop Cap depends on how many planets you have, the normal Pop Cap is 20, and let's say that each planet, adds 5, there are +43 planets in the game, and you have control of 20, then it should be 100, plus 20, it would be 120, also, there might be a Limit Pop Cap, but we know that 20 osn't all, you just have to take over planets, and build stations. This is just expeculation, also I'm talking about the Galactic mode, in that mode, there will be a lot of hudge battles, in skirmish the Pop Cap also increase by the reinforcements points you have, so the Pop Cap CAN be a lot bigger. Edit: I said this in another topic, but it fits here
