People saying gaming sucks now but you need to specify here, AAA gaming sucks. There's a lot of amazing indie games coming out all the time. Even the AA scene is seeing a bit of a comeback. Plus there's just more games out there. Companies are dumb for raising pricing and forcing all these micro-transacations because there's just more games to compete with. The classics aren't going away.
Why should people spend $70+microtransactions when you know the AAA gaming scene releases broken messes? You can go buy The Witcher 3, which still looks amazing, for less than the price of a sandwich when it's on sale. You can buy so many amazing classics for dirt cheap during sale times.
The problem isn't gaming is entering it's worst era, it's that the only games you play is the heavily marketed big budget slop instead of doing something so simple like going to a dedicated gaming board and saying, "I like games X, Y, and Z, what would you recommend I play?" Or even just Googling "Best <genre> games of last 10 years." You'll find so many amazing titles so quickly and never get around to playing all these amazing games.
Just for the sake of experimenting, I searched "best action platformers of the last 10 years." The second result was a Reddit post where the top comment, ignoring all other comments throughout the thread, had 31 games series, not singular titles, series of games recommended. That's just one post of one genre. There's no way people can't easily find new games to play.
