Contested Continent

I would be cool if you could make a "second" factory on a contested continent. When i say continent i really just mean an infinitly large map, and with contested i mean it as in there being othe entities on this continent. That way you can expand your factory by militarily expanding. A large map would also allow for more advanced and longer range logistics like trains. But capturing land on land would mean adding ground based combat, not to mention enemy ai's. All in all I would at the very least like an infinite continent which you can start expanding into later in the game; so as to enable longer range and more sophisticated logistics like trains, because as it stands trains won't really be that usefull on such small islands.
