Characters we can relate to have fears and damage, but moreover, for me they have to be devoted to something - an ideal, a person, whatever. Even villains become much more sympathetic when we're introduced to whatever it is that they love.

It's enough to say "He climbed into his hovercar" and your reader will get the idea. You don't need to give a geography lesson: "They were sitting in the courtyard drinking fire-palm wine" or "She trudged back from the well, balancing her water jar" or "They looked out across the desert and saw the yellow mountains of Califia before them" all give brief, intense impressions of a place, without stopping the narrative in its tracks or drawing focus from the main character.
