Hi, I see, thanks for your thoughts. I often have similar feeling, but in my case it mainly caused by the fact that I like multiplayer/MMO games and current multiplayer/MMO games are trash, and old one I loved to play have servers offline for a long time now.
Maybe you should just relax for a little and switch to something else like tabletop games, or even to movies/series/books.
The only recommendation I can give you that worked for me a few years ago - try VR games if you still haven’t. I guarantee that you will be positively shocked by experience even if you have just a headset (you don’t need a west, a treadmill, etc.). The cons of that solution is the you need rather powerful PC (the best VR games now exist only on PC, games that run directly on a headset 90% of time are bad) + you need to buy a VR headset (but I recommend you to buy used one, Quest 3 for overall ok experience, Valve Index if you have money, Quest 2 or Pico 4 if you low on money) + there is only a bunch of VR games exist that are worth playing, so after a while you may be bored.
Nice to see you tried VR already. Yeah, VR games are in hopeless condition unfortunately. I really hope I can return one day, maybe Steam Frame release will change anything, we will see.
Thanks for sharing that webpage with retro games, appreciated 👍
