Let me first say that I had no interest in Black Ops 2 initially. Like many, I thought I was done with the Call of Duty franchise as each year it became more of the same. However, I rented Black Ops 2 and that changed very quickly.
The campaign is probably my third favorite (behind Modern Warfare and Black Ops). I did not think it was nearly as great as most say it is. I really don't mind since I play through the campaign once before I delve into the real purpose of the CoD games..the multiplayer.
The multiplayer is far and away the best since Modern Warfare revolutionized it about five years ago. Since 2007, it is been more of the same with more tweaks here and there, but this game allows for alot of customization. Multiplayer has so many options to fit your play style especially with the Pick 10 style. I can go into a game with no grenades if I want and stock up on perks. Also, the emblem creator is better than ever with more slots and customization. It's a fun way to express yourself even if some user emblems are not exactly PG rated.
While there are some technical issues and the game is not perfect, the game is the most fun I've had playing online to date. I've owned it for a few weeks and have already put in over 100 hours and I haven't felt even begun to get bored.
