What really made halo 3 great besides the gameplay mechanics and music was the balance of vehicle parts and parts where you are walking. Halo 4 has an amazing campaign I'm not denying that, the story behind the campaign was genius, but one thing they could improve is adding more vehicle stages and also making a wider variety of vehicles available to the player, especially flying ones, we need some hornets, maybe if there were some more scorpions, choppers, mongooses and hornets, the campaign would be a little more interesting.
