...the more people rate a game, the more weight the ratings have...
Good luck ! BGG ranking is a complete mystery (and IMHO severely bogus).
Let's compare Netrunner and Through the Ages.
Netrunner has a better average rating (on par with TS) and not so few ratings (only 1400 less). However, the geek rating is way lower, and it is today #4 when it should be #2 (or even #1) for months...
I agree that DW deserves a bigger success.
