Getaway. 7 years so far. I’ve seriously put it on the block a few times, but never sold it. The problem is, the game is perfect. I’ve taught so many people about real Pinball on it. The game has easy to understand rules, and it can be explained quickly. And when people start playing it, the game is a blast. I’ve lent it out multiple times. And I even had it at my work for a few months, where people played it constantly.
I just finished it’s second shop job since I’ve owned it, and it’s playing awesome. So I’d expect it to be my longest owned game for many years to come.
