This generation is only starting, think about games from early PS4 vs nowadays. I think they haven't even begun using the power of these systems bc most games are still coming out on last gen. I bought the Xbox Series X bc of the studios Microsoft bought and what they produce. Arkane studios doing games like Redfall, Bethesda making Starfield and Elder Scrolls 6 eventually, Tango Gameworks, and more.

The Series X hasn't been worth it yet but I will be keeping it for years to come. So in 5 years, 10 years whatever it will have a ton of games I'm still trying to catch up on or play again. We are just in this awkward between phase bc of the pandemic delaying games and chip shortages preventing people from getting their hands on the systems. In a year or 2 when all the games are exclusively current gen your PS4 won't cut it.
