I've played this game since 0.14 and I've got to say resources would mean just as much to me as docking was. Also the problem with build a Duna base or Munar base is whats the point once your already there walk around the surface for hours and hours? Or building and maintaining a mining colony with In-Situ Resource Utilization in addition life support could then afterwards be added to the game and would make it so much easier to keep your kerbals alive once resources are implemented.
