There is another thing that Mae DU different from Eve beside that everything will have a cost, either financial and/or men and ressources.
We will need to explore the universe and creating trade routes, business hub like JITA and that create some interesting game mechanic like that:
Your corpo found an interesting system and decided to open a trade route by installing a Stargate between that said system and Alioth's system. Your interest will be to secure those gates because you can collect a traveling fees, and if you failed to protect your customers, sooner or later another org will open a gate with stronger protections and more services like escorts, insurances and whatnot...
Thinking of it, we already went there in the XVI-XVII centuries when the major European powers sent ships everywhere to open and secure trades routes from/to Africa, India, Asia and such and it was fair game for those companies to 'reduce' their competitors by any means.
And remember, a war is won with money, not men...
