I mean realistically has Mario been any different since Mario 64? Outside of graphical updates the core gameplay idea has never changed.And there's nothing since like that. None of the great games- sequels or not- are fundamentally different than stuff I've played since 2015. So what are you supposed to say about Spiderman 2 other than that "it's more Spiderman." It is and there is just no world where it would make any kind of "impact." Cannot and should not compare to Mario World coming after Mario 3 which was like a whole new thing completely. Tech hit a point of diminishing returns.
Gaming is limited quiet severely in terms of what gameplay can do. The Witcher 3 doesn't play any differently than any of the Ubisoft open world AC games.
Gameplay ideas are not really evolving, and they don't really need to. Because a fun game is a fun game regardless of how many times you play it. People have been golfing for 100 years, playing Baseball, Soccer, Football etc. Gameplay is fine.
What really matters and what tends to "blow your mind" is presentation. The story, the characters, the setting, the art design, that stuff is where people lose their shit and call games masterpieces.
And this might be why people think gaming sucks these days, because this new generation of writers and game makers are too busy making political message vechicles rather than games. That's why we don't get Dragonage Origins, we get Veilguard.
And it's also why when game unaffected by that SJW messaging, it gets huge news. Stellar Blade, Black Myth Wukong, are just solid games with a clear vision that made a solid game, because they didn't care about what reviewers in the West would say. Which didn't PCGamer shit on Wukong because there were no "women" in it, but that's only because they didn't make it far enough in the game to see the women.
Expedition 33 does fuck all differently. But people love it because the presentation (and hype over rooting for the "little guy" even though they had big publisher funding). That's what get's people these days. The gameplay just has to be decent and everyone will love it.
