The best one from your list would be the one where people start out with ARs and find weapons on the map. That’s what he had with the old Halo games.
Team Slayer.
Slayer FFA.
Big Team Slayer.
Capture the Flag.
Assault.
Infection.
Race.
Territories.
Grifball.
Oddball.
King of the Hill.
Invasion.
I could go on and on. My point is, we can’t play these gametypes as they were (or even similar to) in the previous games due to them either not existing in Halo 4 or to the embarrassing lack of custom options.
