I was rather sceptical about this game since so many reviews and blogs stated it was just another re-hash of the former NSMB for the Wii. Since I love all Mario games I still got it (expecting to enjoy it but still feel bugged about all the supposed 'drawkbacks' people were talking about).
My mind was soon changed and I was completely captivated by the crisp, beautiful graphics of this game. I'm still not quite over my initial surprise. The small videos throughout the game are a great addition and the background scenery to the stage really makes you feel like your in a BIG world compared to the former game. There are many nostalgic touches like the return of baby yoshis - which are just awesome - and boom boom as well.
There are a lot more new things in this game compared with the wii version such as the titles for each level, the world map, the videos throughout the game, yoshi abilities, different challenge modes, squirrel suit - the list just goes on. The twist in the storyline actually makes a big difference in my opinion.
So far, this games has just been pure enjoyment and bliss - I go into my own content world when I play it, the stages are extremely captivating and engaging. I'm enjoying the music as well.
I don't think this game needs to be compared with NSMB Wii because this just blows it off the scale!
If your thinking about getting this game, I wouldn't hesitate in buying it, despite what more picky people may say about it.
