Centipede, of course, is one of the most well-known early arcade games, featuring a trackball-controlled avatar firing lasers at on-screen centipedes and mushrooms. Star Raiders isn't as well known. It's a first-person, Star Trek-style space exploration and combat simulator released on various Atari computers -- as well as on Atari 2600, where it used the "Video Touch Pad" controller.
The fact that these are on Gamefly suggests that they're retail releases -- since Gamefly doesn't rent downloadable games.
