Parts. Two Taps, a Clip Tile, the Double Inverted Slope w/Cutout, some Clip Plates, Grille Tiles, Technic Pieces, Barraki Eyes, a Printed Studless Slope, and a Minifig Handlebar are the things that catch my eye.
Build. A one hit piece of Terrain and an Attack Buggy.
The Questions:Can you build something -- a frame, station, or starship -- right away? Yes. (+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? Yes. (+5)
Score: +5 (B+). A decent score for a City set.
