This is more for the people who have a wide interest in games that they play, but there are certain games that they just dislike and won't play. I, for example, absolutely hate Pathfinder and D&D 5E. When I look for games to attempt to join, since the games I like aren't widely played, I'd like to do a search for games in the LFG tool, but exclude listings for Pathfinder (or D&D 5E) to see if there is anything going on that I would be interested in. Since upwards of 70% of games tend to be Pathfinder and D&D 5E, and since Roll20 really is optimized for those kinds of games, it makes sense that they make up the vast majority, I'd just like to exclude them to find something I'd be interested in playing.
