I enjoy older games because they're much better compared to modern games. I recently bought a couple PS4 games and I really didn't play them that much. I spend more time enjoying older games, the only good thing about the PS4 is that I can use it's controller on the Pi.
An another thing I like a lot is finding great retro games. For an example I have a couple romsets and often I just load up a random game, you'll be surprised how many good games there actually are.
For some reason retro games really grab my attention when playing them, I have ADHD and usually I have a short attention span so I get bored easily. But with retro games I can play the same game for many hours without getting distracted (or make some lame excuse to do something else lol).
I'm a SNES fan and I think anyone would agree with me if I said that the Donkey Kong Country series have aged pretty well. The games still look great and the music is timeless. IMHO one of the BEST games on the SNES. I noticed that older games have a lot of replay value, nowadays with games its meeeeh. It's just graphics, DLC and multiplayer.
