But we've got 4-5 decades of games to enjoy.
Part of the reason that the games industry is struggling is that there's been no real generational leaps for a long time. Gaming used to be driven by those technological leaps, but these days we just get incremental improvements. 10-15yr old games are just as entertaining as brand new releases and often don't look too dated.
Also, ever more people are getting into retro gaming, enjoying the classics from the 80s and 90s, from well before microtransactions and hyper-competitive online multiplayer.
