End of Nations - gamefront.com

From Universe at War developer Petroglyph comes a mix of real-time strategy and MMO gameplay that looks like it could be a lot of fun. The developer is giving you a persistent base that serves as your operations center outside of any battles or anything like that. It’s sort of like your house in an MMO, and as you make progress throughout the game you’ll be able to drop down additional buildings and produce more units. For instance you’ll get an armory to buy and sell items and send things to friends and a headquarters where you can view and modify your army.
