I had a dream that at the hour the NSO Earthbound icons rotate to the ones for Mother 3, a weird new menu appeared on the NSO app on the Switch.
I clicked on It, and got transported to some sort of roguelike version of OoT: I had to look for weapons around the map, defeat enemies on closed rooms and look for Mother characters hidden around them. I made It to the place where Link falls down to Termina and becomes a Deku in Majora's Mask, and when I defeated all the enemies there and found Lucas and Kumatora... A textbox appeared saying "now Earthbound World is available, wanna try?". I chose yes.
And at that point, I was playing a whole official NSO exclusive release of Mother 3, called Earthbound World. The main difference from the original Game was that now instead of It saying "Welcome To The World Of Mother 3" at the beginning It said "Welcome To Earthbound World".
