Minifig. I like the Translucent Yellow.
Parts. The Pale Greenish Yellow color is interesting. The "A" frame Plate is a bit weird. Besides that
it's a fairly standard collection of Plates, Modified Plates, Slopes,
Mixel Joints, and Clip Tiles.
Build. Either a flying Frame or a Frigate for IO. You choose. :-)
Can you build something -- a frame, station, or starship -- right away?
Is it below, at, or above the golden ratio? Below. (+5)
(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: +10 (A-). Not a bad set, I just think it's better as a parts pack than the core for a build.
