I saw from the Nintendo Switch trailer that some games can be played by 4 players across 2 Switches, by putting the Switches next to each other.
I saw 1 game which looked like baseball, with 2 players on each switch, with each Switch showing a different perspective of the same game, and another game where they were matching a Banana across 2 Switches, and another game with tanks shooting each other.
Which games were shown in those examples? And where can I get a list of games that can be played with 2 Switches?
Does the game need to be purchased twice? Or how does it work?
