The number of games and sports based on hitting, striking, kicking, throwing, or passing etc., an object such as a ball, must amount to thousands.
These games have ingeniously and exhaustively exploited the balls size, its shape, its weight, its rebound, its flight, and so on.
Here comes the halfbaked bit - apart from juggling, which is a recreation rather than a game, I dont know, after a search, of any competitive games which use two or more balls simultaneously; it seems to be an unexploited area.
I visualise wild experiments such as playing two soccer games on the same pitch with differently coloured balls.
Or an entirely new game with one half of each team restricted to kicking a round ball, and the other half to passing-running with an oval ball.
