1979 Stern Hot Hand. The huge constantly rotating flipper on top is loud and annoying, and since you can spot cards up there all day, the drop targets are sort of pointless. Totally uninspired generic backglass art. Just a whole lot of "meh" on that game for me.

Orbiter 1 had the potential to be a really great game. I love the art, the spinning pop bumpers and the 3D playfield. Also very cool to have the ball go safely behind the flippers, but not fun when it drains from there. I'd buy one if the price was right.

X-Files is also a fun game. I wish there were more of them in other people's homes.

Around 1998 the Dave & Buster's (which was actually Jillian's at the time) had a MB and a South Park side-by-side. I played them the same amount and liked them about the same. I could tell MB was much higher quality, but I though SP was more fun. And before I get spanked, I was 34 in 1998 and had a kid on the way.
