Idea: When multiple games have the identical players, map, and settings, then don't list them all in "join a game".
Specifics: Instead, have one of them there. When someone joins the game, add one of the additional identical games to the list so that people can either join the first one, or join the second afresh. Keep adding them to the list once they become different from the template.
Why: It would remove a lot of clutter from the page, make it easier for people to find a game quickly, and fill up some of the multiple games a lot faster for those who want to start a lot of games with the same settings. It'd remove a few pages from the kind of games I look for at least.
