Well nobody would miss the shitty campaign in CoD or BF, but I think that Titanfall had the potential for an amazing campaign.
Just think about it. 1st person parcour with a jetpack and shooting, fighting against and with titans, etc. I think it's a shame they didn't even try.
But still better than making a worthless piece of crap like CoD and BF, they at least don't try to fool anyone.
