Maybe you could limit the size of a company, instead allow unlimited alliances between companies. That way it's easy to finally finish making a new corp. as an expansion of your old corp. A nice thing about the limited resources is that you could solve one of the oldest problems in MMOs: economy. It's easy to see why most MMOs have this problem: there is no economy. As my old Economics teacher put it: Economy is the science that studies how to spread limited resources to people with unlimited wants. The unlimited wants always are there, but in most MMOs there's also unlimited resources (in the sense that a sword is just *spawned*). Maybe with limited resources (and the fact that people will have to *make* everything) will allow for a more complex but stable ingame economy.
