Slugfest came out around the peak of my baseball obsession as a kid. I spent untold amounts of tokens trying to pop a ramp up so I could hit a pinball over it and win some baseball cards. I could have saved that money for college or something, but would that be as fun? Probably not.
Who knew in the 90s that the pinballs that were being nearly given away after the death of the arcades would appreciate more in value than Ken Griffey Jr's rookie cards?
