Adding a disclaimer stating that they know the review is really negative but guys we swear the game is totally still worth 9/10 you have to believe us guys doesn't make the review any less negative. It just shows that even the reviewer realizes how ridiculous his score is coupled with that review.
It's like, "it's nothing special, but it's a Super Mario game so it deserves a 9/10!" So was New Super Mario Bros. on the DS, and that was nothing special. So what makes this so good? Oh, it's like the original New Super Mario Bros. except very little of the content is actually new this time and what new content there actually is is okay, but doesn't really add much to the experience? Oh, okay then.
Actually, checking the website, they apparently thought that New Super Mario Bros. was 6% better, so they must have really hated this game.
I'm not saying the game isn't great, because it very well may be, but that's not a 9/10 review.
