I'd say more shifted toward hardcore, rather than being a mix of casual and hardcore. I've been playing video games since my younger times, and spend hours on them. I think I played over 100 different video games!
I have hardcore playing habits, but I enjoy more casual games, like Animal Crossing, Harvest Moon and Professor Layton. Heck, I think the single most hardcore thing I've played is Final Fantasy VII. (Or X, depending on how you look at it.)
