A post on GameSpyDaily has word from the folks at Big Huge Games that Rise of Nations, their upcoming era-spanning RTS game has suffered a slight delay, and is now expected for release on May 20. They indicate this decision was made to allow time for some tweaking based on the feedback from the game's ongoing beta testing. Also, CDV sends word that No Man's Land, Related Designs' RTS of exploring the new world, is slated to ship this summer. To celebrate, there are some new screenshots on the game's website, showing off its use of real-time shadows.
