The United States finally gets its proper game show about video games although Video Power didn't start out that way. At first the series was an animated show about a guy who teamed up with a rag-tag bunch of characters from various Acclaim Entertainment video games. In its second season, Video Power switched up into a game show where contestants would play through five rounds of trivia and NES and Gameboy gameplay.
Here is the intro for the first season.
And now the second, more Vanilla Ice-ish season.
