PS4 and PS5 have produced the greatest single player games of all time. Nostalgia can be a strong influence.
Even with nostalgia goggles on, PlayStation 1 and 2 easily had more good games than SNES and Gameboy Pocket.
SNES has some absolute gems and a fairly deep library of legit good games, but most Gameboy games are barely better than most NES games and rarely hold up to anything even in the next generation of handheld Nintendo games.
If I were to make a list of greatest single player games of all time there would be very few PS4 titles and absolutely no PS5 titles.
You say this, and yet I re-played Deus Ex a month ago on whim and it was still probably better than 100% of all games in PS4/PS5
I don't have the time,the budget or the hard disks to bother with trying them out.
Which you can only enjoy right after you finish creating your Ubisoft account. Or your EA account. Or your Bethesda account. Even though I want a single player experience. And if I refuse to create an account, I am unable to pay for the game I just paid $60 for.
All of that on top of a console that is constantly showing me ads and forcing me to login somewhere.
