I've recently became fascinated with this generation for the first time in my life.
These consoles were essentially the Cambrian Explosion of video games. Before the Explosion, the most complex animal was a jellyfish(aka pong consoles), but then after the explosion we started seeing crab relatives(aka Fairchild F) and octopus relatives(aka Intellivision).
Another reason I've become fascinated with this generation, is I've learned theres so many other consoles in this generation besides the Atari 2600, and ones with better graphics and sound.
So basically these were the consoles that existed before the revolutionary NES came into existence.
Now I am a fan of playing games on original hardware, but this generation kinda makes that unappealing to do. Theres 2 things I don't like:
1. insanely outdated video connections
2. exotic controllers
I do know theres ways to get around this. Like you can use a Genesis controller on a 2600, and combined with an S-video mod, those problems are gone. But thats not the same solution for every console.
You can easily tell by my post that I did not grow up with these consoles, and they predate my existence by a decade. But I'm sure theres tons of members here who grew up with these consoles and could share their stories and advise to newcomers interested in them.
