Tastes like...PAPER!
In a good way! Nintendo is really good about polish, presentation, and character, and the latest Paper Mario installment is no exception. The game is also a strange blending of genres, not quite following any rules, so I'm just going to say it tastes like a well-baked 'sticker adventure.'
Paper Mario: Sticker Star is all about the stickers. I feel like Intelligent Systems has taken the "everything is paper" meme even further this time -- impressively further.
