Have a set list of playlists such as Team Slayer, Snipes, Rumble Pit, your standard Halo playlists etc. and let people choose the games they want to search within those standard playlist.

For example: If someone wanted to search Halo 1 and Halo 3 in Team Snipers, they could select those 2 games in the lobby then search that playlist with those games to try and find others with the same set criteria. This is how many people, myself included, thought MCC was going to be in the first place. Doing this will cut down on quitting, dodging, and create a MUCH less toxic environment within matchmaking.



If population is an issue and fear of people not finding matches with what they have selected, at least let it try to search that criteria for a few minutes and then offer an option to expand the search.
