I certainly don't advocate cloning EVE at all. However EVE is/was groundbreaking in terms of its economy because it is (apart from the artificial and inflationary infusion of ISK through ratting/incursions) a "real" economy. Absolutely everything is player made by raw materials that have to be mined for one way or another. Absolutely all the prices are set by players and the market as a whole. So if DU is aiming for a player-driven economy, similarities to EVE will necessarily develop. It would be foolish both to repeat the mistakes made in EVE and not to try to learn from what has been proven to work - and hopefully make it better.
