Top Ten Plug It In and Play TV GamesIf you don't know what Plug It In and Play TV Games is, these were known as Handheld TV games where you buy a product that has built-in games to a game controller and you plug that in to play on your TV. These were sold often at Gamestops, but now you can't really find these things anymore. In any case this list covers some of the most known ones.
Most if not all of these were made by Jakks Pacific, a toy company that is surprisingly still around today.
Plug this controller in to play 10 Atari 2600 games including Asteroids, Gravitar, Yars Revenge, Realsports Volleyball, Breakout, Circus Atari, Centipede, Missile Command, Adventure, and Pong (just a small part of Video Olympics).
