There's really nothing we need to say about this gameplay footage for Super Mario Galaxy 2. However, we don't like five-word posts at Destructoid. There are other blogs you can go to if you want that kind of brevity. So, I'm simply going to cheat and post a description of root beer.
Root beer is a carbonated beverage originally brewed using sassafras. Root beer, popularized in North America, comes in two forms: alcoholic and soft drink. The historical root beer was analogous to small beer, in that the process provided a drink with a very low alcohol content. In spite of roots being used as the source of many soft drinks in many countries throughout the world (and even alcoholic beverages/beers), the name root beer is almost unused outside of the United States, Canada, the Philippines and Australia. In Australia, it is most often branded as sarsaparilla. Most other countries have their own indigenous versions of root-based beverages and small beers but with different names and branding.
Oh, and Super Mario Galaxy 2 looks straight boiler, dawg.
