Ok I was thinking since you guys updated today you added the squad slayer and everything I was thinking like it would be awesome if you could make like a custom games matchmaking where 16 players are in a lobby and they just pick a host and they use their maps and things that would be pretty cool if you don't have any friends online.
Another idea is you could make like a playlist for racing and the sub-playlists would be like challenge maps ovals and twisty tracks and stuff idk but that would be cool.
My last idea is if you could bring back some of the halo 3 maps in a map pack like you did with the halo 2 maps like longshore and last resort.
