Quoted from modfather:

Nintendo killed it for the pinball industry. With plenty of games to play sitting on the living room , Momma didnt have to drive you to the gameroom with a pocket full of quarters. Once Sony playstation hit the market, it looked just as good as the arcade versions. Mortal Kombat was Hot because of the ultra violence it delivered and kids ate it up. It looked and played just as good as the arcade version, thus saving plenty of quarters for me. Pinballs didnt deliver the blood and gore kids really clammered for. Plus the really good players would post up and challenge any new comers, and get destroyed within minutes. To rub in the insulting defeat, FATALITY !! ..and rip your spine clean out of your body.
