The games dropdown menu exist to help standardize the options
available (example: 4E vs. 4th Edition vs. D&D4, etc). No matter how
many games are listed, some may not make the cut. Games are added to
the list periodically. This ensures obscure listings gain greater
visibility when sorted via the Other Games option and helps keep away “empty” search listings for underrepresented titles. If
you feel a game should be listed, encourage your community members to
play and post often. The more community attention a title receives the
more likely it is to be added to the list.
