I feel like I'm the only person that likes halo 1 4v4, but its not easy to play logistically and people would obviously rather play 2v2s. There used to be the playlist and sometimes 8s lobbies on MCC but other than that no one really was interested. Pretty much agree with everything Hard Way said, slayer kind of sucks and KOTH's random rotations don't help. Most of the bigger segmented maps (Derelict, Creek and Damnation come to mind) can be fun as you have room to breathe
