I think this could be a great idea for a new pinball title to differentiate itself from the others. Multiple rulesets in one machine. So maybe there's a simple rule set with just a couple of challenges that would work for beginner players, or at locations where there aren't hard core pinball players. Then one or two advanced rule sets to add challenge and fun for advanced players.
This would be great for tournaments - if a pin had multiple rule sets and one of them was very simple and very scoring balanced, that would make the pin a good choice for tournaments (in contrast to the titles that get pulled out of tournament pools for having unbalanced scoring).
This would be great for home use - switch up the rule sets for kids, n00bs vs experienced players.
This could even be great for locations - start with one rule set, and as time goes on and players have gotten tired of the machine, switch to another rule set and extend the life of the title at that location for a while.
