Build. A naked quad walker design.
Can you build something -- a frame, station, or starship -- right away? Yes. (+5)
Is it below, at, or above the golden ratio? At. (0) (The Golden Ratio is $0.10 per part.)

Does it have more than a handful of immediately useful parts? Yes. (+5)
Score: +15 (A). Another decent score and this set also has some interesting parts.
