True in a sense but I wouldn't call COD a rpg or a hybrid. Many genres of games have rpg elements now. It adds a lot more depth and replayability to a game that wasn't there before. 

I used the CoD example for the single player. I suppose every game with a campaign or a story mode is going to have the most basic RPG elements (a fictional setting, a protagonist and a some elements to advance the story), but that is kind of the point of this thread, to difference the RPGs from the rest of the games.

If you look at the division and compare it to halo, COD or GTA, the differences become more obvious between RPG and other genres.
