Quoted from pinballcorpse:

In theory I get it, but it sounds like this is going to open its own can of worms. We will definitely need to see the official details.
The way I read it, every event at a unique house or location could be a "major", depending on who shows up, how many games, etc.
Local clubs and metropolitan areas with many collectors, or good players, or numerous locations are going to have a field day cashing in SCS points. It is going to punish those who do not live near the pinball hot beds or know many collectors in their state. It will be exponentially worse than trying to travel to a major show for 3 days.
Further, with private collectors hosting, space will be an issue as well as the potential for exclusivity. That is, it is doubtful many private collectors will want every player across the state showing up at their home looking for WPPR points.
It will be easy to exclude folks even if the event has to be advertised. The general city is known ,but even now some events read "Private location, contact director". So, with space an issue, one could see where some non local people are excluded in favor of locals. Sorry, we never got the email request, all spots are filled.
Majors used to be at shows or large facilities, where the public is welcome and the tourney is open (for the most part, Pinburgh comes to mind as it tends to sell out).
Unless I am reading it wrong, the irony will be that winning a PAPA circuit event in a state could be trivial compared to the sum of the day to day points available, which seems counter intuitive to what the intent of a state and world ranking of players should be.
