My favorite Atari 2600 game was Kaboom, but these days I mostly play retro games on the NES. After all, the Atari 2600 is an old clunker, and although I'm emotionally attached to it and have a pretty decent cartridge collection, I only switch it on occasionally.
Well, I still enjoy playing classics like Pitfall, River Raid, Pop Eye, Super Cobra and others. It's true that I much prefer them on the Atari 800XE, which I've had since I was little and which has graphics on another level, but I also enjoy playing them on the Atari 2600. I have a cartridge collection too, and it needs dusting off now and then :)
I agree about Pitfall. It was definitely one of the best games for the Atari 2600. All the games from Activision were great, really. Decathlon, for example, was another fantastic one. And then there was Missile Command from Atari — that was great too.
I enjoyed a hide-and-seek game, but I don't remember what it was called. Does anyone know? It started outside a house, and the first player could hide anywhere outside or inside the house. Then the second player took a turn and had to find them. I'd love to try that again after all this time :)
I had an Atari as a kid, and Popeye the Sailor was probably my favorite. Pitfall, Missile Command, the hide-and-seek game and pretty much everything else were great too. We had so much fun with it back then. It's not the same today. Those good old days when computers and computer games were just getting started.
My favorite game had this funny little character walking around a department store or something... escalators... a green background... but I can't remember what it was called anymore.
