Original Atari 2600 my father bought for my older sisters. Yar's Revenge, Super Breakout, Defender, Missile Command, Pitfall, SeaQuest, E.T., Combat (the pack-in), and a bunch of third-party stuff, some of which is unplayable or makes no sense.
Stuff like Bugs--
Though some was pretty good, like Dragonfire--
Or Venture--
I even have this INCREDIBLE game about the band Journey, named Journey Escape. Seriously, it was awesome.
