Atari 2600.
Combat - Tank battle game (had planes too).
Pac-Man - Awful version of the arcade game.
Asteroids - Not so awful version of the arcade game. My uncles would play this for hours, breaking the scoreboard repeatedly.
Space Invaders - Didn't actually play this one much.
Oink! - Played this one a lot with my dad, building my brick house which he would huff, puff, and attempt to blow down.
Enduro - Pretty cool racing game with day/night/snow/fog effects.
Starmaster - Space combat simulator. One of the coolest games ever for the 2600, this even used the difficulty switch as a game control to bring up the galaxy map
Warlords - Possibly the first 4-player simultaneous home video game? 4-way Pong with paddle controls and each player defending their own base. Hours of fun with 4 people.
And yes... I had E.T. as well.
