I understand what you mean, though I disagree. When I compare the experience I've had from playing games like God of War, Last of Us 2, Uncharted 4 and Horizon Zero Dawn, they all differ greatly. I went though different emotions and gameplay didn't feel the same at all. They all managed to really affect me, one way or another.
Add to other AAA SP PS4 games to this roster, like Spider-man, Ratchet & Clank, Detroit, Last Guardian, Shadow of the Colossus and Until Dawn and I feel this has been one one the best generations ever.
I do agree with you on some level, mostly thematically they can be alike. That's the reason I haven't played Days Gone yet - it looked like a buggy TLOU.. but hey, I think I'll give it a chance now that it's all patched up.
I am obviously exaggerating a little bit for effect, I am not saying that they're completely the same.
But they sorta exist in the same bubble if that makes sense.
I also think that Spiderman does too, the base gameplay and mechanics are very similar or even the same. Ratchet and Clank is one that actually does feel different so I'll give you that but also mostly in tone and visuals. But that's honestly enough to make it stand out.
I'd just like to see more games with stylized characters and designs, and as much as I actually prefer third person myself maybe some first person games too.
Like imagine for example a game like Nier Automata, Yakuza or maybe even something a bit unorthodox for consoles like a Diablo styled game or a RTS game.
What's especially annoying about it is that the Japanese already do this well, and Sony is a Japanese company. And yet they don't take advantage of this at all.
Sony games sorta feel like the Marvel movies to me, big blockbusters very noticably aimed at the mass market where everything is shiny and fairly tropey.
But I think that audiences are receptive to other things too.
Right now it just sorta feels like their first party studios are all working with the same fundamental building blocks with all of their games and it's kinda boring imo.
As much as I loved the RE2 remake, part of me was kinda disappointed about the gameplay changes for this reason too.
Imo the remake of RE1 still holds up, and it'd be really cool to see a big budget game do something cool with that.
But we just keep getting games that sorta play the same.
