Isn’t that how we got
Sonic Colors,
Sonic Generations, and
Sonic Lost World? Those are very simple stories, and in some cases, simple to a
fault. Like, let’s go over it again: in
Sonic Lost World, the main villains are “The Deadly Six.” Formally, they are six creatures known as “The Zeti.” What are they? Where did they come from? We know absolutely nothing about them. All we know is that they exist on some weird sky-planet called “The Lost Hex.” They have the power to control robots, apparently, and their one weakness is the tone emanated from some kind of magical conch shell.
The story is that Eggman uses the magic conch to enslave the Deadly Six in order to do… something? I mean, Eggman already controls robots pretty well, given he’s the one that builds them. It’s never clear why he needed to enslave them, outside of hassling Sonic. Sonic trashes the conch and Eggman loses control of The Deadly Six, after which they immediately double cross Eggman and assume control of his factory, which has a machine that begins sucking the life out of the planet below them. They then spend the rest of the game doing absolutely nothing of value while Sonic and Eggman team up against them. Eggman also largely does nothing of value, but Sonic systematically defeats all the Deadly Six one by one.
Then Tails gets kidnapped and Eggman supposedly dies during the final assault on his stolen factory. Sonic defeats the Deadly Six one last time, possibly even killing them, and rescues Tails. Eggman returns to reveal this was his plot all along and you re-fight the final boss of Sonic Colors again, but worse this time. The End. To this day nothing has been revealed about who the Deadly Six were, what their purpose in life was, or even if there are more than just six zeti (one of them mentions having a mom, so probably). We don’t even know if they lived peacefully or if they were imprisoned on the Lost Hex planet. Are they just intrinsically evil? If so, why? Nobody knows. They also all seem to have powers besides controlling magnets, but nothing is ever said about those, either.
We don’t even know what happened to them after Sonic beat them the final time. They have never actually returned in any official, canonical capacity – Zavok turns up in Sonic Forces as part of the returning rogues gallery, but he’s a holographic copy created by the Phantom Ruby. It’s not the real Zavok. The real Zavok, along with the rest of the Deadly Six, might actually just be dead for all we know (which, let’s be honest: that’s fine.) They were super super nothing villains in a nothing story that whiplashes between
obnoxious Saturday Morning Cartoon vibes and being weirdly serious for no reason. And whereas some other Sonic games can have over an hour and a half of cutscenes,
Sonic Lost World barely manages 30 minutes of (incredibly disjointed) story.
When you say “Sonic should stop trying to be epic” all I hear is
Sonic Lost World. I know you said character-focused, but I’m not entirely sure what that means, and your example of Gamma is forgetting that Gamma’s Story in Sonic Adventure was part of the larger “epic narrative.” Gamma tied in to the idea that redemption is always possible in some form or another, and that’s what saves Chaos in the end. But there’s still a whole stretch of Sonic games that tried to focus on smaller amounts of narrative with less heavy drama regardless. Even The Time Eater was treated as decidedly non-important in the end. Again, sort of like The Deadly Six, it was just something Eggman found out in space, apparently. No back story, no personality, no drama, just a big weird clockwork monster that eats time somehow, apparently.
I dunno. Sonic’s always touched on ancient mysteries and epic narratives ever since Sonic 3. The
Japanese instruction manual for that game literally sets up the core of what became Sonic Adventure’s whole narrative. It’s been there since the Genesis games. The Archie Sonic comics, for all of their soap opera drama, set a record for the longest running continuous licensed book in the entire comics industry. There was a time where it was outselling everything Marvel and DC were putting on shelves. Archie’s book continued a legacy from the Saturday Morning Cartoon, about a grim dictator struggling against a small band of rebels living in the forest.
Like it or not, but “big epic” stories have been a significant, notable part of this franchise, and is something people come to Sonic specifically to experience. They tried to simplify things and it ended up turning to crap, so now they’re going back in the other direction again. Hopefully Ian Flynn can make something out of it, but it’s important to note that Sonic Team themselves still came up with the story, and Flynn is just… adapting it, I guess? As part of the localization process.
