I forgot Zelda. I love Zelda but the gameplay difficulty is hard as hell so I'm not sure if Ill ever get a Wii. And therefor I'm not very well informed about sales/titles either.

Someone do a reasonable speculation on Zelda sales this gen (Wii only).

only zelda majora's mask was hard TP and wind waker were very easy, puzzles and combat very easy my 10 year old nephew beat them without using guide.
