In case you missed it, Nintendo has now issued a reminder by sharing a fact sheet on social media - highlighting a few of the fun details about each game. It's also shared a link to the original EarthBound Player's Guide (again).
Here's a refresher on both games:
"Join Ness, Paula, Jeff and Poo in their quest to fulfill an age-old prophecy to stop the wicked Giygas (and maybe catch a Runaway Five concert along the way) in the fan-favorite Super NES classic EarthBound. In addition, travel back to 198X for EarthBound Beginnings, a localized version of the original Famicom Mother game. Both EarthBound and EarthBound Beginnings are coming to Nintendo Switch Online ... later today!"
