I though the mmo part of the multiplayer was set up to similar to
http://www.boundlessplanet.com/, But its not. Boundlessplanet took all the players on one server 50 to 300+ players and put them all on the same GIGANTIC map at once(true MMO). The game went on 24hrs a day you simply logged in and did what ever you do to your base. you can atack anyone on the map 24/7. I provided the link so you can read up if you like.
