When I first started doing set reviews I was rating them based on intuition. That allows for a lot of personal interpretation and over time things will get sloppy. Which is no help for any of you when I'm doing building block set reviews as you're looking for fairly concrete information as to why you should, or shouldn't, buy the set I'm discussing. So I decided to be critical about why I'm being critical. I've come up with a series of questions and attendant point values that will give a clearer picture of how useful a set may be.
Can you build a frame, or frames, right away? (Yes = +5 / No = -5)
Is it below, at, or above the golden ratio? (Below = +5 / At = 0 / Above = -10)
If you can't build a frame right away, does it have parts you should be able to put into use right away? (Yes = +5 / No = -5)
Does it have more than a handful of immediately useful parts? (Yes = +5 / No = -5)
Added to a base score of zero (0), the answers to these questions should give a range of -25 to +20 points. Which gives us the following scores and ratings:
+20 = A+
+15 = A
+10 = A-
+5 = B+
0 = B
-5 = B-
-10 = C+
-15 = C
-25 = C-.
I'll be using this system from now on for my reviews.
