Depends what your definition of a kid is.
I always say that I got my skills on Gottlieb EMs as a kid. Funny thing is, Williams got my attention big time with titles like Superstar, Travel Time, Gulfstream and El Rancho.
Bally continued to lure me in the golden years with Lost World, Supersonic, Playboy, Kiss, Star Trek.
Then came my 2 favourites Black Knight and Firepower.
That's it, I then became a big kid.
