Not sure as to how or what direction you are taking this game, but I have idea that I believe would bring a nice twist to the game. when players finally find utopia. flip the script and turn it in to a mission base survival game, more tech to be learned, giving better gear and such. maybe missions to help keep utopia running and functioning. missions that take players out in to the depths of the area around utopia to add to the game play, with co op in game this would bring even more game play to this already great game, but like most survival games you get to a point of board and what is the point of playing. So turn market on its ear and give this game a twist when they get to utopia. Just idea
