console games are generally more "casual-friendly", not in a bad sense, but in the sense of "picking it up and playing for half an hour". personally when I play pc games I feel like spending quite awhile on it.
also, the comfort levels of console gaming, to me a controller is just more comfortable in my hands, but also the added benefit of sitting halfway across my living room from my tv.
also specific console-only games. Naughty Dog for Playstation games comes to mind.
