Up until WaW I used to do the same, couldn't get tired of the 4 and WaW SPs and occasionally played MP when I was bored. But from then onwards I found the SPs as just add-ons. I hate it when they focus so much in MP, it's not that hard to make a great multiplayer game, but it's way harder to make an enjoyable singleplayer.
