Way back when I bought my 1st machine I had to leave it at my parent's house for a week or so. My dad said 'NO WAY is that coming inside. Keep it in the garage, and it has to take up as little space as possible.' (Their garage is filled with movie equipment and such, so it wasn't like they were losing a car spot over it.)
My mom wanted to play it, so I set it up. (Game is a FH, BTW) My dad didn't understand why I bought one, said it was a waste of money, etc....
Until he played.
Now my dad grew up extremely poor, so there simply was no money for pinball when he was young 50-60s), and never had the chance to really play one.
So what happened is he finally played FH, and LOVED it. The second day it was there he spent 8 hours straight playing. No food, no breaks. Next day, almost the same thing. He had the garage door opened, and their neighbor heard the noise, and came over. He stayed until after midnight playing the game with my dad.
Funny part is, the neighbor was on the way out the door to mail his taxes, and the date just happened to be April 15th. Well, he got so caught up playing, he never mailed the taxes out on time. They were late, and got hit with the late fee.
The next weekend when I came to pick it up, my dad said it did not have to go, and he REALLY enjoyed playing the game.
Now when they come over, he always heads straight for the game room. His current favorite is Earthshaker, but he is really looking forward to the bowler getting fixed.
All my co-workers and employees know I collect and play, and they come over fairly regularly to play. When my boss found out, he wants to come over the next time he is in town.
