Quoted from Pinballgeek:As for me I have a rule that once it's gone it's not comming back.
The only rule in pinball should be "Don't have any rules". That way when you change your mind you are not breaking the rules.
I've only done it 3 times, and I don't regret any of them. In each case, the replacement was a better copy, and I liked the game. And giving it some thought, if I had space, there are 3 others I'd bring back given the right circumstance.
