I agree with 99% of that, except physics .... if you were talented enough to be a PB designer and be heavily into physics, that would be one hell of a machine. you could get the ball to roll against gravity, pass it's inertia on to another ball, an object in motion tends to stay in motion bonus!, have skill shots set up where if you bank it just right it hit's 5 separate targets in a row all over the table ...
pinball IS physics ..... but the math it would take to make a table based on it would kill a man.... lol well me anyways.
Another bad idea for pinball table themes, any sitcom from 1995 onwards. Anything by tyler perry, ....
