This companion can sorts your boardgamegeek collection by game mechanics and category.
It can also list the expansion you do not have for boardgames you own. It takes only the owned boardgame, exclude the expansion and ignore multiple copies of the same game.
It may take a while for boardgamegeek to generate the collection and you may have to try again.

Enter you the Boardgamegeek username and press submit.
