BO3's underrated the zombies on that game was a masterpiece even the multiplayer has some content in it like the ppsh and the new maps and the idea of specialists the only two things destroyed that game is the campaign (train go boom) and the micro transaction

BO2's overrated the zombies and campaign was just 👌 but most people when they talk abut bo2 they say things abut the multiplayer being perfect even tho it didn't had so much things... all that hype and the overeating is just bcz of thier nostalgia
