Favourite call of duty game?

Hands down ones of best cods is BO2, the whole vibe that it gave off was amazing. All the futuristic music, storyline, and multiplayer made the game such a joy to play. In addition to that, the BO2 era was the prime of many cod content creators, Vanoss, Ali-A, etc. I just get so much nostalgia just by thinking of the game.
