Hey Pinside, I stumbled upon Jon Norris' Blog today, and I found this post to be an interesting read: http://www.norrispinball.com/blog/?p=30
Pretty much when Jon was designing game tables for Gottlieb, he got to pick The Legend of Zelda for a pin theme as part of a Nintendo license deal that had already included the completed Super Mario Bros and Mario Mushroom World games.
Well, when Gottlieb secured a new license for the American Gladiators TV show, the Zelda design switched to American Gladiators, while keeping the same table layout. Then, when the American Gladiators license fell through, the table was re-themed again to Gladiators!
It's interesting to see Gladiators pinball and wonder what it could've looked like as a Zelda or American Gladiators themed pin.
