I agree, but I also think kids nowadays find it interesting too, but hell, they find Fortnite interesting too, so maybe Palworld is gonna be the next big thing for them now (if it survives the hype and the pass of time).
A bit more about nostalgia, I remember I played Pokémon Red and obviously watched the anime too, but then I saw a magazine advertising Pokémon yellow and showing Jesse, James and Meow, I was like WTF I need to have this, plot twist never did (not physically at least) but at least I continued with Fire Red, Ruby (never finished it) Diamond and Platinum, Soul Silver and I kinda stopped there, currently playing Omega Ruby because yeah, nostalgia, oh and yeah I finished Pokémon yellow recently in Anbernic RG351V, so a very good way to achieve it if you ask me.
It would have been interesting if they released more games like Pokémon yellow (making it easier to feel we are in the anime).
