After reading through the kickstarter (I was not involved in it), it looks like we got what was funded, plus a bit more. Especially on the PvP side, since no new PvP modes, ships, or guns were part of the Kickstarter. The entire world map thing was not funded either, yet we have it. ttps://www.kickstarter.com/projects/musegames/guns-of-icarus-onlineadventure-mode
As far as free roam and the other requests, that is basically an entirely new game. I don't see it as a feasible thing to include in the existing title.
