Parts. There's a couple of the Mod. Plate w/Arm Up, a Cone, a 1x2 Cheese Slope, some Technic bits, Wheels and Rims, and then there's the Motorcycle Frame and Cover.
Can you build something -- a frame, station, or starship -- right away? No. (-5)
Is it below, at, or above the golden ratio? Above. (-10) (The Golden Ratio is $0.10 per part.)
If you can't build a frame right away, or choose not to, does it have parts you should be able to put into use right away? Yes. (+5)
Does it have more than a handful of immediately useful parts? No. (-5)
Score: -15 (C). Honestly, I bought this set just for the Captain America minifig.
