I got it yesterday, got 25 shines so far...
The camera just sucks, its the only down point of the game. I find myself moving the camera almost as much as I move mario. I have found the game to lag in some places too (1st world 8 red coin challenge when your jumping on those ropes) Also the game is only good in 30min pieces... anything overalll that u'll throw the controller @ the wall forsure. Like the reviewers said it is a hard game, which is good because it means you get your moneys worth (unlike luigi which i beat in 2 days), but on the down side once I beat it I doubt I'll play it thur more then 2 times (it'll probably end up on ebay)
