I would love to see a networked 'challenge mode'.

Unlimited balls, first to hit the left orbit gets a point, first to hit the right ramp, first to hit a target a certain amount of times, first to start multiball, first to a certain score.......you get the idea.

You could play against anyone or more importantly someone you know. I would prefer to see networks used for challenges rather than just high scores.

Sorry if this isn't really an innovation.
