While searching for games, I suggest making this very small, but very handy, change:
Rather than having those circles you can select only one of, have boxes which you can check. In this way one can search for a few of their prefered types of games without having to do many searches (takes up bandwidth).
This also will allow people who're willing to play anything but one or two types of games to simply remove them from their results. This will be conveniant.
Everyone wins, no downside.
