Parts. As you can see there's not a hell of a lot here.
Build. Go Kart. 2Rh+d8 (Hulk
Smash!) 1B (4 Wheelin'!) 1Gd8/2W.
Can you build something -- a frame, station, or starship -- right away? Not really. (-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). Awful. The stickers may be the only reason to buy this set -- and, yes, they count as a part.
