Combining playing video games and physical activity! What more could you ask for?
Well, ummm...you run around on the PowerPad(TM) to make the game sprite move. Usually, it didn't work all that well. By the end, when the computer guy has beaten and laughing at you, you're pounding your fist into that stupid pad's embedded microprocessors, which of course is only making it worse. But you really don't care at that point. Oh, and since running and jumping around are involve, not only are you pissed, but you're pissed and exhausted! Isn't that fun!
Graphics and sound weren't too bad, especially for its year. You certainly clearly saw the jeer on the computer jerk's face as you're standing there, all sweating and swearing and crap, shaking your soaked fist in anger.
And there you have it.
