What gaming generation is the oldest that you still regularly revisit? And what keep you coming back to it?

I play regularly on PS5 Pro and semi regularly on PS3.

Although I rarely use the original hardware nowadays, I fairly regularly play SNES, Game Boy, and early-to-mid 90's PC games.

For somewhat regularly, it's got to be the 7th generation. I still have a lot of interesting games from that generation in my backlog, so it's only natural to keep coming back to it. I don't think generation matters a lot for me, it's the games that matter - but going back too far in time sure introduces some issues, so there's not as many appealing games the further you go back in time.

After what I said, it should comes as a surprise that I do occasionally play games older than that too. It's just not often enough that I'd call it regular enough for the purposes of this thread.

I still play through SNES games every year - it has many all time favourites of mine. It's the console that properly got me into gaming, and one that I have many fond memories of playing. Plus, the games have held up well and are still fun nowadays.

Zelda a link to the past

Older final fantasy games 7 - 10, typically play them on switch 2 or ps5

Never really kept older hardware due to money issues back then.

GameBoy

Currently have both SNES and Genesis hooked up and playing the crap out of them (though I really shouldn't; sometimes in the night, I hear arguments; and once, I woke up and found the SNES with a bruise under its right switch; looked nearly purple). But I also keep the NES permanently hooked up, as well, so I vote third. Still the king of 2D, imo. Nothing has ever been as dominant, market share and pop culture wise. It's the GOAT for me.

6th Generation is the oldest I boot up right now (and I can play PS1 games too which are 5th Gen). Just got a PS2 Slim. PS5 is the "oldest console" I regularly use right now in terms of hours played. I have a Switch 2 which is of course newer.

6th Generation is such a vibe. Compact consoles (GameCube and PS2 Slim), plug in and play, some really cool games. 

Does PC count if I'm emulating? I love doing modern QoL enhancements, and will play games as old as on the NES (e.g., Super Mario Bros 1, 2, 3, and the Lost Levels).
