It's the best game of all time, hands down. If you haven't played it yet then get that shit immediately!
Wouldn't go that far, but it's definitely a must play in my opinion. Great story, great gameplay, great graphics for last gen.
The multiplayer is what makes it the best game of all time. If you were into that then you were really fucking into it. I have never had so much fun with a video game in my life, and probably never will again. At least not until the next one.
10/10 would definitley recommend, ive played it all the way through atleast 3 times. get the GOTY edition and hop on that undead nightmare too after you finish the story
It could have used some additional side activities (especially criminal stuff), but its still a great game.
