Didn't you hear that for every person that brown noses Gary Stern, they get a free game that Gary drives to your home and personally sets up for you.
I have a lot of respect for Gary for keeping pinball alive through the dark ages. If it wasn't for him, we would be all playing 90s games without hope of anything new. They are the reason we can buy new games without having to pre-order or wait and hope that boutique manufactures are able to raise money and ship. 3-4 new titles a year, like clockwork.
Do my two Stern games have bugs? Yes. All software does. Have I ever had a moment of diminished enjoyment from my Stern games due to code? No. Not once. They are great big toys and I enjoy them for what they are; objects to enjoy and amuse.
Having some perspective about this conversation makes it a lot more fun to enjoy pinball.
