People who buy pinball machines are people with tons of extra money to burn. A $750 price hike on a $9000 game is an 8% increase. Anybody locked in on a Premium won't run away from 8% imo, so these prices are here to stay.
For me, it's the overall product that will decide if I'm in or out. For example, I think I'm out on JJP forever. The flippers are terrible and always have been. The scoring on JJP machines is terrible and always has been. And finally, the ruleset on JJP machines are mostly terrible and always has been. They won't change the most crucial aspects of their games, so there's no way I'm shelling out money for their products. If Stern quality ever goes down this path, that's when I'm out. It won't be because of the cost.
Spooky is close to being out of my life forever as well. I've purchased 3 NIB games from Spooky and they've all had issues, either hardware or software, that ultimately led to me selling them off. Scooby Doo is the final straw, but I'm pretty confident this game is a turning point for the company. If so, customer for life right here. Literally all in or all out from this point forward. I've purchased more NIB from Spooky than any company.
And then there is American Pinball, who has quietly had the best everything when you think about it. Prices? Check. Quality? Check. Rulesets? Check. Scoring?... ehh... could be better I guess. But this company has implemented so many amazing rules and features and moments that I haven't seen in any/many pinball machines before. They aren't afraid to take chances.
....... ugh.... I have a Scooby on order, I'm looking to buy FF pro, and now I'm talking myself into buying the next AP as well......... lol. I hope it's expensive as hell so I can talk myself back out.
