The problem is, that many on here have short attention spans, and don't keep a game over 6 months anyway. And most don't know how to do any work on them either. So serviceability is farthest thing from their mind. Just throw money at something different, but new enough that they don't think they will have to fix anything. 2-6 months later, it will be sold and they will go to the next thing that is hyped up.
But anyone that has been a collector for a long time, and fixes their own games, know that these new games are going to be a problem 5 + years down the road. When Stern is off to a new system, or shot themselves in the foot so much that they are no longer in business. Now we sit with no replacement boards and can't fix the ones we have. Plus the documentation we have available is piss poor to say the least. At least up until Spike, pinball tried to be serviceable. It's not a disposable item. You got documentation to service it, and the components were workable. If you needed parts, the company had game specific parts available for a time for things like ramps and plastics.
I love my ghostbusters, but at the same time, I always think about selling it, because it doesn't look like it has a long term lifespan. If it's not fixable 10-20 years from now, I don't think I want it in my collection. And I won't be buying anymore Spike system games.
