The generational leaps aren't as big as they used to be. As a gamer who started with the NES, I've experienced that feeling of playing a game for the first time that is leaps beyond anything I've played before it. I didn't have a gaming PC until the PS2-era, so the first time I played the N64 (Mario 64) was the day after playing a game like Donkey Kong Country on the Super Nintendo. DKC, arguably the best-looking SNES game, cannot be mistaken for an N64 game.
This is me just being a realist. Now as a gamer who enjoys being hyped up for new tech and great games, I'd love to buy into the narrative that the PS5 is going to be like nothing we've ever seen before it, but things are different nowadays.
It's great to be optimistic, but ridiculing someone for their "opinion", which to me is a perfectly legit "opinion", is just kid shit.
