You know what I would like to see? The option to add your custom game in a list so that random players can join you in your game. The list works by listing the game type, map, and a brief description of what to expect before joining. This will make playing custom games on user-created content much easier, would allow for some diversification from the game types available and would enhance the ability to replay the game.
Restrictions can be applied to who you let in, and who can put there games up in this list to ensure better quality. You can apply restrictions based on level, or games played for example.
