There were more games for the intellivision, and some very good ones, like Pitfall, and astrosmash. but the intellivision had that strange controller with the center disc. But the Colecovision also had a strange controller, IIRC. I think it was a very short, stubby joystick that you had to move with your palm. Which is why I say that the Atari 2600 had the best games of the era, with a decent controller. Only graphics was better on the last two systems.
