To assign a score to each mechanic, 4 things are considered.
Top 100 most played games of all time on BGG
Top 100 most-rated games of all time on BGG
Games with BGG rating of 7 or more.
All available BGG mechanics are assigned an initial score of zero. Then, the games in the above list are processed one by one.
The score of a mechanic is incremented by one when it is found in a game. This process is repeated for all the three lists above to arrive at the final score.
