Nevermind the generational leaps, there has been a lack of creativity and a flood of low quality titles that make it harder and harder to find the few good games among them.
I've had better luck finding great games I didn't know about from the 1990s than from the past twenty years.
It seems to me that the indie games scene has shown quite a lot of creativity.
But how do you discover the good ones?
Top ten lists written by indie gaming bloggers for each year/genre are a good place to start, honestly.
If you like 2d platforming exploration types, try Hollowknight, Celeste, VVVVVV, Ori, Animal Well. Each one is fantastic.
Where do you find trustworthy top tens?
So far, only Rusted Moss and Silksong were worth my time among the platformers I tried, which included the original Hollow Knight (platforming is too easy), Celeste (too easy A-sides, unfun B-sides) and Animal Well (too easy base game, too cryptic post game).
