Thanks for the quick reply and the info. Thinking more broadly, one of the challenges as a buyer and player of ttrpgs is finding new games that suit my taste. An approach I'd like to see a big enough site use is for me to click on a game I already know I like and find out, say, that of the 100 others who like the game, 40 also like game x, 35 like game y and 28 like game z.
It would give me a little road map to explore new games that others with my taste have enjoyed as well.
