I remember the show you mean but not the name. I loved the first series of it. It was a Mortal Kombat arcade machine. The game had just (maybe was about to) come out then. If I remember right that wasn't even the best prize there was a mystery thing he could have gone for but he didn't risk all the cool stuff he'd already one. edit - I wanted to remember the name too now so I googled a bit and found it. It was called Games World
