I've just added almost 5500 titles for the Atari 8-bit Family systems. The Atari 8-bit family included a variety of systems ranging from the Atari 400 to the Atari 1200XL. Some of the notable games that came out for the Atari 800 were Donkey Kong, Frogger, Deluxe Invaders, Atari Invaders, Preppie, Sea Dragon, Missile Command, Asteroids and many more. Honestly, this system brought into people's houses some of the best arcade games and it was no wonder that the Atari 8-bit systems did so well. There's a really great video on youtube on the 60 best titles for the Atari 800. Definitely worth a look:
