I used the idea of MMS, as it works very well if you want 100's of AI roaming around, as you can effectively reduce the rendering distance dramatically, with the right blend of terrain/trees and fog and make a very large map.
Game play is linear which is a trade off, Gameguru isn't ready yet for rolling hills and a million entities, but when the time comes, and gameguru is ready and I have 6 months on hand I will definitely would like to do a more open world type game.
