CoD probably. Note that I only really play the SP for these games. Used to be really obsessed with those games in the early days with CoD1, BRO and CoD2. Then CoD4 came and was a game changer. W@W, BlOps, MW2 were all excellent. Probably around Ghosts was where my interest started to wane, that game was really bad, and after that they pretty much plateau’d. And aside from Infinite Warfare, none of them really grabbed me like those in the Golden era of CoD(4-MW3, W@W-BlOps 2)
