Much more complex and much better as well.
One of the biggest tasks actually being discussed right now in the official forums is the enormous undertaking that is getting to the center of the Milky Way. People are already planning and setting up expeditions to try to map out a way to the center. One person can't do it alone since there will be fuel costs, enemies that people may encounter, etc
You guys have to remember, that everything is to scale in E
and David himself has stated that he doesn't expect anyone to get to the center for a while. Another problem is that "human space" is limited to a very small amount of star systems so people would have to really plan out trying to get to the center.
I personally can't wait!!
