Wii, definitely. In addition to SSBB and Mario Kart, our humble little two GameCubes duct-taped together has Endless Ocean/Forever Blue, No More Heroes, Agatha Christie, Baroque, DQ Swords, Destroy All Humans, Okami, Opoona, Alone in the Dark, Nitro Bike, Blast Works, Rygar, de Blob, and Lego Indiana Jones, among others.
"'Casual games' are something the 'Game Industry' invented to explain away the Wii success instead of actually listening or looking at what Nintendo did. There is no 'casual strategy' from Nintendo. 'Accessible strategy', yes, but ‘casual gamers’ is just the 'Game Industry''s polite way of saying what they feel: 'retarded gamers'."
