Quoted from wdennie:But I want something that has a build quality that will last 20 years, not a throwaway game.
I think Stern is smart to move towards less user serviceability and a shorter lifetime model for their games. Especially since it doesn't seem to affect their sales.
Edit: That being said, the best way for a game to stay in service is for the manufacturer to stay in business to offer replacement parts. Short of that, the pinball community is great and always seems to find a way to keep games running.
