I never bought it. I still play the first BO though. I got a bad taste in my mouth from MW3, and didn't feel like shelling out money for another COD, even if it was from a different developer.
Zombies really is a pain without someone with you. It's especially difficult if you are playing it for the first time and have no idea what the heck to do or where to go. It is definitely a multiplayer mode.
I don't know if I'm going to get Ghosts, though. I was looking at maybe getting Battlefield 4 instead. I've never played BF3, but a lot of my friends who have played it tell me that the MP is better than COD. Regardless, if I do get one of those, I'll probably wait a few months to get it so that the price will go down (being a college student makes me more and more of a cheap bastard everyday).
The Last of Us is definitely a good game. It has a really good story that keeps you interested in the main characters, much like The Walking Dead video game. The stories aren't too similar that it feels like the same game, and both are different gameplay experiences. The gameplay of TLOU is like a cross between Tomb Raider and Hitman: Absolution.
I don't actually own the game, but I watch a playthrough of it on YouTube by Shenmue36. I've watched a lot of his other videos, including his Tomb Raider playthrough. When I say TLOU gameplay is a lot like Tomb Raider, I just mean the way that you move around and upgrade your weapons and such. Tomb Raider was a more boring story to me, and failed to keep me engaged the entire way through. TLOU still has me completely engaged, and the story has much more believability than Tomb Raider.
Shenmue also has videos out of TLOU multiplayer, so you can watch those to be the judge on how good the multiplayer of that is. It's fun for me to watch, but not enough to make me want to buy the game.
I used to play a lot of Assassin's Creed: Brotherhood multiplayer. That was a very fun game to play. The problem is that no one really plays it now, and the MP for AC Revelations and AC3 is not very good, to put it kindly.
Other than that, the only other multiplayer games I own are Gran Turismo, NCAA Football '12 and '13 (I don't plan on getting '14), and NBA 2k13. A lot of games that come out I am able to watch playthroughs of on YouTube. This is what helps me be a cheap bastard.
