Quoted from Spock:For example it should be done in a way where the remote device controls a toy, mini-flipper, trap, coil etc. that player #2 or 3,4 etc can control and sabotage or change the gameplay for the other player while they are playing
Agree, there is much potential. Would be cool if player 1 is enjoying and epic ball... player 2's "killer app" lights up on his phone providing an option to disrupt player one. Like a menu with Lights Out, Lights On, Reverse Flippers, Weak Flippers etc... Player 2 gets to wait for the right moment, select his option and KaPow! The game goes berzerk for a second and implements Player 2's selection. Player 2's selfie front and center on the screen to taunt Player 1.
Fun stuff.
