Would that not be 4 nations?
Or was there no limit on the number?

Edit: Building on that question; how large of a landmass is reasonable?

You mean the size of your nation? Youc can make it what you want, if it makes sense. If you want to take half the continent to make a big empire, okay, as long as it fits with the world. Just be considerate to leave space for other people.
