The biggest reason I care about this is if I ever need to sell one of these games down the road, I'm going to get beat up on the price and have a hard time selling it for something that isn't normal and isn't my fault. Now I don't plan to ever sell, but that's always going to be in the back of my head in the event a medical or house emergency comes up.
I know games aren't investments, and I don't buy my keepers as such, but historically most of us haven't lost much money on these things on average and I've gotten pretty used to that. If jjp fixes this tomorrow and doesn't make this right for current owners, my potc is now worth significantly less. Only option at that point is do a full playfield swap.
So that's my take on it. It doesn't affect playability now, but it's not just about playability.
