Todd Howard, Elder Scrolls V: Skyrim Design Director has said that Activision's Call of Duty franchise is hardcore and its multiplayer portion has an RPG elements.
In an interesting interview to Gamasutra, Todd said, "You look at Call of Duty, the most popular game in the world, and that's actually pretty hardcore. At the end of the day, it's a hardcore game, has RPG elements in multiplayer, making classes, picking perks. I think the audiences are there, and we tend to make our game more for ourselves and other people who play a lot of games."
