I have to ask, how can there be so many people on a planet? i mean earth right now, could probably not support more people than it already has which is 6 bil..... so how can one planet have 100 billion people! that's a ton! so my question for all of you is, will there be pop. limits based on how big the planet is or how many useable tiles there are? because that is one thing I did not understand about galactic civ 1. or could someone try to clear me up on how in the world 100 bil. people live on the same planet?
