I'm thinking about creating a list of pages about various genres of player-created games. So far, it's only Free-for-All Shooters, TowerDefense, and Escape Rooms. I've created stubs for Interactive Stories, Adventure Games, and Disc Golf Maps. I'm thinking of a page for Parkour Games and maybe Pick-Up Games for games that don't rely on circuits to implement rules (i.e. most of the games that you currently find in the category Player-Created Games).
Any other categories that I'm missing?
