Parts. There are a lot of Plates and Modified Plates in this set. Only two ball joints though. Two of the new tooth pieces as well. Honestly, although it has two of my favorite piece -- 1x2 Plate w/Bar (open ends) -- I'm not that thrilled with the selection in this Mixel set.
A quick 4P Mech. I'm statting this one up as 2Rd+d8 (arm missile
pods) / 2Rh (flamethrowers) / 1B (back armor panels) / 2W.
Can you build a frame, or frames, right away? Yes. (+5)
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? Yes. Barely. (+5)
Score: +20 (A+). We max out the score on a Mixel set but, this one barely squeaks through.
