Stuff Share Tweet Pin Here is one you do not see every day. This is a Gottlieb Challenger from 1971. Only 110 of these were produced back in the day. How many are still around now all of these years later? One can only guess…but not too many for sure. This is a concept that has been tried with a few other machines such as Joust that came out in the 80’s. None of they really caught on. Although playing against an opponent in this fashion looks to be great fun to me. I have never seen one of these in person. Thankfully there are some videos of the game on YouTube. Something cool to add to your game room if you appreciate unique games and have the space. Not sure what the reserve price on this is. Considering the rarity who knows?
