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.
