Thanks Lonnie for verifying me.
One on One was designed by me in late 1995 and we made a few (three to five) prototypes in early 1996. The game was an arcade novelty game based on the existing arcade hoops style games where the object was to make as many baskets as possible during a timed game. It had an adjustable "Catch-Up" feature, where if one player fell behind by 10 points, their baskets would score more points.
The game was never made because Gottlieb closed in July 1996. I do recall seeing at least one of these sold at the liquidation auction in late 1996.
A side note, I also designed an arcade novelty drag race game that used the same principle except that target hits advanced your car up a drag strip and the first car across the finish line won. Instead of a basket, this game used the drop target arrangement from Hot Shots, with standup targets replacing the drop targets. The cabinet was a side-by-side style rather than a head to head style. That game was titled "Eliminator" This game was done around 1990 and never made it past the whitewood stage and was killed when the company went to the street line design philosophy.
