Combat: Probably the most famous VCS title of them all. I don't want to go into this game very much, but even though it's more common than sand, it's still a great pile of fun if you've got friends around. Spend thirty minutes kicking each other's butt in a game of tanks, and then try rebounding shots. Then move on to planes. I love this game when I get friends over to play it with, and it's just great. I hate finding this game at the thrift. The stories about me giving my spare combats to people at drive-thrus, water parks and the box-office is completely true. How else are you supposed to get rid of them?
Warlords: You can use two sets of paddles with this game and then have a four-player battle. Back then you could get the entire family in on a game of Warlords, and it's the game of choice in large classic-gaming tournaments. It's a variation of breakout, though you have to cooperate more than anything else to avoid dying.
Math Gran Prix: Now, Atari couldn't make solid games and not get criticized that their system wasn't educational, so here they created several educational titles to appease the parents.
Basic Programming: I had this game, and it came with the special keyboard controllers that allowed you to program it. Though I was never able to learn anything from it! :) Apparently they never thought that you'd write more than about nine lines of code, since the program does strange things if you try.
Game Program Case: I have one of these, and it's just a cheap plastic folder for you to store your carts in. Apparently they didn't think you'd ever own too many, since there's only room for eight carts in it.
