One of the best parts of being a Nintendo Switch owner is how often you find yourself saying “Whoa! I didn’t know my Switch could do that!” This was certainly the most predominant exclamation in our war room after the reveal of Super Mario Party at E3 2018. Now, having seen the dual-screen mode, dubbed Toad’s Rec Room, in action, it’s safe to say our shouting was justified.
Toad’s Rec Room a set of four fun little diversions from the Mario Party we’ve all come to know and (mostly) love. This mode lets players pop off their joy-con and utilize the Switch’s hidden screen sharing ability. This isn’t screen sharing in a “traditional” sense, this function basically turns your Switch into a giant Nintendo DS, creating one larger image across both screens and spreading the touch-screen functionality seamlessly across the larger play area. Rec Room challenges include matching sets of bananas, pummeling each other while piloting tiny tanks, playing three innings of baseball, and fourth mini-game that has yet to be shown off.
