asteroids, duck hunt, Missle command, Battlezone (altough the arcade Battlezone was much better)
Timex / Sinclair 1000: 1K chess
Bandits (the Vic's small screen made this a FAST game!), radar rat race.
Text adventures like Hitchikers Guide, Winter games, Caveman Ugh_lympics, world games, and Zaxxon!
I'll end there, I'm showing my age now.
