Me, I believe in the importance of the single-player campaign experience. I always will.
That being said, I've little doubt that Call of Duty: Black Ops II will offer the superior multiplayer action. While I believe EA's Medal of Honor: Warfighter will also be strong on that front, and I also believe the BOII campaign will be worth playing, I would still take Warfighter . And if you could only pick one shooter this fall and you aren't completely obsessed with multiplayer, I'd recommend the same.
The authenticity and realism of EA's game should be fantastic and I think that's what sets it apart. Not that I don't mind a little arcade-y-type fun in my shooters, but I had to admit that Modern Warfare 3 felt a little…old-fashioned. Granted, we're talking about Treyarch this year, but I will always maintain that Danger Close's Medal of Honor was underrated. Yes, the campaign could probably be finished in only four hours time, but I think the single-player quest in Warfighter will be longer. Plus, EA has tapped just about everyone they need to tap to deliver a memorable campaign.
It's the difference in focus that matters. I know EA realizes that shooters mostly sell on multiplayer appeal, but based on everything I've read, heard and seen, the developers are really putting a ton of effort into the new MoH's campaign. You really see a lot of heart and soul in there, and that shines through. I'm almost convinced that the intensity and true feel (relatively speaking) of Warfighter will make Black Ops II feel like…well, a video game. That's a big distinction.
