i was having issues with this game (and other unity games) not starting. What i figured out is that unity doesn't like it when you have more than one video driver enabled at once. If you're having issues with the game crashing as you try to launch it (and don't have Citrix installed) then try to see if it works when you only have one video driver enabled. If you do have citrix installed, then try uninstalling it because that also can cause issues with unity launching.
