       | and Ace Combat?

       | I want to dogfight over Ohio, land at Offutt to play Warzone in
       | Omaha, then take a MRAP and drive to NY.

         | The difficulty of making a "large" map comes from what you want
         | to simulate and in how much detail, not from how big it is per
         | se.

       | How do these two compare?
