I fell like this is one of those "not if but when" situations. Spotted via Nintendo life, It appears the the ESRB website has been updated and it looks like Super Mario Galaxy may be making it's way to the Wii-U via the Nintendo e-shop. This would make sense considering the second game is already up there. No word yet on a release date.
Now, I hate to do this, and I really hate to be "that guy" but.... I wasn't really a fan of these games but I fully acknowledge that it's pretty much my fault for getting my hopes up every time a new Mario game is released.
You see for me, Super Mario 64 is one of the favorite games of all time and my favorite Mario game of all time. I still play it to this day and all I want is to get a. Sunshine and Galaxy are fantastic games, I am not saying they are bad, but neither of them could capture the charm and fun of Mario 64 in my opinion. The closest game to do so in my opinion was Super Mario 3D World for the Wii U.
