LEGO Rating

I like to review the LEGO sets that I build. But, the question arises, how do you rate LEGO sets consistently so that you can compare sets of different sizes, costs, and themes? Well, I have devised a rating system. There is some inconsistency in my early set ratings since I have been developing this rating system as I go, and I will probably continue to modify it as new things come up that I have not considered yet. But, this is a description of how I am currently rating my sets.

Value

After reviewing several recent LEGO catalogues, I have determined the current average cost per brick for LEGO. This will obviously change with time, but as it stands, here is how I rate a set (prices in Canadian dollars, score out of a total of 5):

  • <$0.10 per brick = 5
  • $0.10 – 0.12 = 4.5
  • $0.13 – 0.15 = 4
  • $0.16 – 0.18 = 3.5
  • $0.19 – 0.21 = 3
  • $0.22 – 0.24 = 2.5
  • $0.25 – 0.27 = 2
  • >$0.28 = 1

Build

Every set starts off with 5 points. A set loses a mark for every thing that really bothers me about it. It also gains a mark for everything that I really like about it. The total grade for this section is on 10. This is fairly subjective, but you are presumably reading my posts for my opinion.

Minifigures

Each Minifigure in a set is graded on 10. To make sets with different numbers of Minifigs comparible, an average of all Minifigure scores for a set is calculated in the end. Each of the following criteria earns a Minifigure one point:

  • More than just a generic face print
  • Double sided face
  • Front torso print
  • Back torso print
  • Full sized legs (I hate the stubby “child” legs)
  • Front print on legs
  • Back print on legs
  • Lots of details
  • Comes with an accessory
  • Comes with additional accessories

In addition to the Minifigure score, I also grade a set based on the ratio of bricks per Minifigure. Each set can get a total of 5 points for this, determined as follows:

  • 1 Minifig per 100 pieces or less = 5
  • 1 Minifig per 101 – 149 pieces = 4.5
  • 1 Minifig per 150 – 199 pieces = 4
  • 1 Minifig per 200 – 249 pieces = 3.5
  • 1 Minifig per 250 – 299 pieces = 3
  • 1 Minifig per 300 – 349 pieces = 2.5
  • 1 Minifig per 350 – 399 pieces = 2
  • 1 Minifig per 400 – 449 pieces = 1.5
  • 1 Minifig per 450 pieces or more = 1

I weight each of these two scores (Minifigure average and ratio of bricks per Minifigure) evenly. I determine the average of the two grades to figure out the overall Minifigure rating.

Entertainment

After completing a few reviews, and timing how long it takes me to build each set, I have determined the average cost per minute for building one LEGO set. I feel that this is an important part of the building experience, because everyone wants to get the most value out of their entertainment, right? LEGO is an expensive hobby, and I used to rate it based on how it compared to other forms of entertainment. But, I felt that did not accurately reflect how much enjoyment I actually got out of each experience. So, starting in February 2017, I have changed my build time score to compare LEGO sets with other LEGO sets.  Based on my last ten LEGO sets, the average cost per minute of build time is $0.71. Right now, on a total score of 5, I rate sets according to the following:

  • <$0.60 per minute of building time = 5
  • $0.61 – 0.65 = 4.5
  • $0.66 – 0.70 = 4
  • $0.71 – 0.75 = 3.5
  • $0.76 – 0.80 = 3
  • $0.81 – 0.85 = 2.5
  • $0.86 – 0.90 = 2
  • $0.91 – 0.95 = 1.5
  • >$0.96 = 1

I also rate entertainment value based on how much I like a set, and how likely I am to keep it built as intended. Again, this is fairly subjective, but a review is supposed to be what I think about a set. Here is how I score each set:

  • 5 = I would not change a thing
  • 4 = I will keep it mostly as intended, but will modify it a little to suit my needs
  • 3 = I will keep part of it, and repurpose the rest of the pieces
  • 2 = I will not keep it built, but the pieces it comes with are good
  • 1 = I will not keep it built, and the pieces it comes with are nothing special

I then average out the scores for cost per minute of building time and how much I like the set. This gives the overall score for entertainment value.

Overall Score

Finally, I take the value, build, Minifigure, and entertainment scores and find their average. In this case, each section carries the same weight and is worth 25% of the overall score that I give a set.
