New Super Mario Bros. 2 is a great game. I got it first thing when it came out. I completed most of it on the first day and then a few days ago I unlocked three secret worlds. It is a great game. There are about 9 worlds. I love the coin rush part mini game where you can play as Invincible Raccoon Tail Mario. The new golden flower power is temporary through only one level and is fantastic too. My opinion on this game is that I love it and it's one of the best games in the universe. You should give it a try on your 3DS if you have one.
