I think it\'s probably assumed that your character has some form of jet pack/EVA suit to move in space at all; if they didn\'t, you\'d just be floating around unable to move yourself. That said, I do quite like the idea of being able to \"upgrade\" your suit to make it faster. It could also be a nice idea to be able to add utilities onto it. A short range repair laser, for example, or a small salvage beam.
