As much fun as I have with the campaigns in CoD, they're only fun because of the chaos and diversity (stealth missions, different environments, vehicle usage, etc). The stories are lack luster and next to useless so I don't see that as a point for CoD. I was never a fan of the multiplayer so I'm probably a little bias but I found it lacked in realism. I know it's a game but one of its "foundations"--by which I mean main argument points--is that it is realistic. I'm sorry but if I shoot someone three times in the spine then they turn around and knife my elbow and I'm the one to die, something is fishy. Again, I'm probably bias. I also feel in CoD whomever saw who first would win the fight whereas in Destiny I feel getting the drop on someone doesn't ensure victory. Which at least makes CoD slightly MORE realistic so that balances the crazy knifing:P TL;DR probably bias but I think CoD lacks story and PvP is bleh. Campaign is still really fun and diversified.
