In my opinion, there is a special kind of satisfaction to be found in being a complete purist, achieving something by being crafty without picking easy solutions, or simply by being skilled, such as redocking a satelite into a cargo bay. Of course, it is entertaining to have new toys to play with, but i think achieving as much as possible, with as little or simple components as possible, yields my kind of satisfaction, in the end, it is just personal taste, of course.
