Not even need a ten years, now only around 2 years there's no more P2E games hype anymore, while I still remember how the crowd and hype about Axie Infinity on the late 2020. The same happen like ICO, IDO, IEO, CEFI, DEFI and so on, it's get abandoned when everyone realize the hype already end. I'd say on 2023 or 2024 there's no one will discuss about P2E again except for nostalgia.
Actually right now the hype have slowed down so I think it won't take 2 years before they finally come to rest. Ico are rare now but I think there are still ieo, ido and then defi. Maybe that's because they are better than ico and some of the projects under these are still useful up until now.
Those who remain are genuine and it's not the hype which drives them anymore. You are right that the memories will remain especially if they are really good like we have been a part of it or we have earn something on that project before they have turned bad. Not only some of the p2e but even the late ico's are still being talked about here sometimes.
