I will be honest and admit that I don’t find most Atari 2600 games to actually be fun; there’s a few gems like Warlords and and Pitfall and Pitfall 2, but I don’t think that home console games started getting really good until the Colecovision. That said, I am perpetually amazed at what some people have been able to pull off on such a weak device. 120 bytes is nothing for memory compared to anything I have written on…
You should check out what the homebrew scene has made. I bought an old system, and garbage picked a CRT, just to play them. Started with Medieval Mayhem, a Warlords remake closer to the arcade version. Then I went on a years long obsession. Champ Games makes great stuff and has taken over distribution of some games AtariAge doesn't do since "Atari" bought them.
I don’t think it works on real hardware but I’m quite partial to Bad Apple : https://youtu.be/Ko9ZA50X71s?si=Ds7WuMgPHeubBNNz
