I understand that this game gets a bad rap as being the game that made Nintendo bland for a while, but I honestly don't think it's all that bad. In fact, I quite enjoyed it for what it is. Yes, it sucks it's the game that "ruined" Paper Mario, but honestly it's not that bad. I actually rather enjoyed getting all the Stickers and Thing Stickers, despite how tedious it actually was. Anyways, don't listen to what others say, and if you're interested, give the game a shot.
Nintendo for characters and music. The song is the title theme from Sticker Star, itself being a cover of the credits theme from Super Mario Bros. 2.
