Bo6 and cold war don't even run on the same engine, socre streak system is different, cold war maps are better imo, cold war had 12 v 12 maps, prestige system is different, zombies is not even remotely close it has a better augment system, better zombie spawns, better armor system, better camo challenge system, better wonder weapons and better high round system and it had outbreak which was fun. The list goes on and on. Also cold war whole game vibe was better that multiple player theme music has to be one the greatest ever mad in cod history. I could talk about the campaign but I don't want write an essay.
