The first game I can remember playing is a Williams Smarty. I will never forget that backglass with the little kid in the lower left corner smiling. I saw that at a campground in Canada IIRC.
The first game that I played a lot was a Gottlieb Majorettes that I played up north in at a campground in Wisconsin. That is the machine that I believe got me hooked. The first game that I fell in love with was Bally Wizard which is also the first game I purchased.
I hope to get a Majorettes for my collection someday.
