Adding a Custom Game search engine will allow people to search & play custom games with other people without needing to relay on friend invites to do so. We should have an option to be able to search for any public custom games available. And even adjust the settings to what gametypes, maps, Halo game, we want. Having Custom games is awesome but its limited on having to relay on friends to do so. This feature will fix that and will allow us To host & play any custom game we want anytime.
Please add in this feature 343i. It could even keep us occupied till you fix those complicated matchmaking issues.
