Well, here's an unexpected treat for your Labor Day: A peek at a Mario game you've probably never heard of and almost certainly will never touch, Super Mario's Wacky Worlds. If the video we found at Unseen64 is any indication, it's likely for the better.
Created for the ill-fated Phillips CD-i by Novalogic, SMWW took Mario out of the Mushroom Kingdom (bold!) and plopped him in real-world locales like Egypt (puzzling!). Though touted as a successor to Super Mario World, it seems this would have been lucky to have been a successor to Hotel Mario.
