Havent bought COD since black ops which confirmed for me at least that COD could simply be a yearly map update as the campaign is laughable 3hrs long.the game hasnt changed in yrs & i got bored with the multiplayer. As far as been a COD killer,its all down to preferance.COD & FIFA sell a bucketload yearly as its all casual gamers buy,its all they know,blindly buying every yearly edition when all they are is a new lick of paint.personally im loving destiny,i think its the biggest selling new IP ever?future looks bright for it.
