Yeah, I think Fast Draw is a very cool game, but the ladies seem to like SO76 more. Haven't quite sorted out why yet. I know my wife and her friend Claire will always face off on this game if it's present (currently two locations in Seattle have this).
Old Chicago is also very cool. Add-A-Ball has this in the back room, it's also one of Mitch's pride and joy machines.
Good point about the bonus scoring, too. 300 is a popular Gottlieb EM, people like that you can score the bonus in the middle of the ball (or whenever the ball rack gets filled up) and fill it up again, especially on 2x/3x balls. Gottlieb should have continued that feature.
