By their means of casual, I'm certain I'm casual, or at least more casual than core.
IMO, SMG>TP >>>>> Wii sports >>Mp3>>>Wii play>>>Chicken Shoot>>>>>>>>>>>>>RE4.
Re4 and Mp3 are core titles, but I don't like them at all. I generally dislike all core games, the mid games are good, so are casual, but core games simply suck.
My problem, is that games are supposed to be a fun thing. Happy enviorments = doubled fun. Re4 enviorments = 1/250 fun. If Re4 was set in TP world, I'm sure I would have liked it, but then again, it wouldn't have been Re4.
The only real core games I'm going to like, that are announced, are Godfather:BhE, Zack and Wiki and FE:RD. So being a casual game, great news for me, great for sales :) MORE CASUAL FOR WII!
