Nintendo marketing manager Robert Lowe has told MCV that the upcoming platformer sequel is a "very different" experience to the one dished up by the critically-adored Super Mario Galaxy in 2007.
However, he expressed confidence that Nintendo's development team has "managed to improve on a virtually flawless predecessor", predicting that it will be the biggest Mario game of all time.
The hotly-anticipated title has already received a prestigious ten out of ten rating from UK games publication Edge, a rare honour bestowed on only a handful of games, one of which was the first Super Mario Galaxy.
Super Mario Galaxy 2 is out exclusively on Wii next month and once again sees the famous plumber tackle mind-bending gravity puzzles in outer space.
It will introduce all-new ability suits such as Rock Mario and Cloud Mario, as well as bringing back trusty dinosaur steed Yoshi for another outing.
