Dang. You're going to have to tell people to take off their bracelets and wedding rings when they play that thing, for fear of wrecking that finish. Fantastic!
Some friends came over recently, and when one guy found out the cab had track and field, he says "Oh, I used to know a great trick for playing that game" and proceeded to pull out a pen, lever it between two fingers and whack at the two buttons using the pen (so as to get the really fast back and forth button pushes that game requires).
I had to grit my teeth from saying anything but the buttons seem to have held up fine.
But my cab's nowhere near as shiny as that!
