I can verify that split screen in either docked OR table top mode is GREAT fun. Played a few rounds with my daughters tonight, and it was a blast. You can even do split screen online matches with others. And single joycon play? Sweet as can be. The basic controls for the game only use direction stick, ZR/ZL, A, B, and Y (with X toggling camera to ball mode on and off). So with single joycons, all of the needed buttons are still there. And no, you don't notice any graphical hiccups while zooming around the field, blasting past opponents, and working to score that sweet sweet goal. For a first time player of Rocket League (I've held out on getting it because I'd heard it was coming to Switch), the offline split-screen matches...as well as multi-Switch matches for pick-up games wherever I go...I know are going to be a hit around this house. I can already feel the adrenaline rush from this game becoming something of an addiction around here.
