I was chatting to Rod (CarbonRod) about this a couple of weeks ago and how this type of gameplay can be adapted to older games. I've been doing this for years to amuse myself with EMs and SS machines ;

I play my Paragon in a 4 player game ;

FIRST player objective is to obtain X2, X3, X5 bonus to Extra Ball through the "Valley of the Demons"
SECOND player objective is to spell out "PARAGON" through any means available
THIRD player objective is to build up the score via the "Golden Cliffs"
FOURTH Player objective is to build up scores through waterfall drop targets and collect via the waterfall

This kind of playing can be awesome fun if you don't have someone to play against. You are playing against different "modes" in the ruleset.
