I don't know about that, Peggle is awesome as awesome pie. Casual and hardcore are really a mindset IMO, all games are casual until you decide a certain game is so good you want to play it a lot more than average. There are some games that people tend to play pretty "hardcore" (I still find this amusing) like say Halo 3 and Assassins Creed, "proper" games if you will. There are also ones that people will only play for half an hour to burn up some time like Peggle. But then there's nothing stopping someone playing some hardcore Peggle and someone else casually playing Halo 3. Gaming is one of my biggest hobbies, so I would put myself under "hardcore" banner, but that doesn't mean I'm one of those people who only plays M rated games because everything else is for kids. I'd say "casual" games probably take up more of my time than "hardcore" games as I'm pretty fickle with my gaming, I'll play something for a week and get bored of it for ages, and I often need something to fill the gaps when I'm finding a "real" game I want to play.
