Will sega ever try to make a serious sonic game again?
While I don't have autism I miss the Sonic Adventure games.

They fucking won't. They did Sonic 06 and after it's result they won't go back to the serious theme ever again, nevermind the fact that it was supposed to be SA3.
That's plausible, but it'll be full of "muh nostalgia!!!" faggotry again. They've placed that bet on Generations and it sold and now they're doing it with that Sonic Mania game that will sell as well since people still do romhacks of old games and it's soundtrack isn't too bad. But since people in charge often misjudge things, misattribute them or categorize reasons of game's success too broadly or mix up major and minor reasons we can expect them to figure out the following - "Games that pander to nostalgiafags sell, sonic games with serious tone do not sell, sonic adventure games are a mix of those two so we'll make the game lean on the cartoony and Lost Worlds aesthetic, we can bag both the new and old audience with this!"

It could be decent - new and improved chao gardens and potential for playing over the internet. But it'll still be mediocre at best.

It's just the end of an era, m8. Like arcades.

You have to consider that the Adventure formula has been done to fucking *death*. Sonic 06 was something Sega absolutely banked upon but workplace incompetence has scared them (and by extension the public) shitless of seeing that tried ever again. That new game they showed might do something similar to it, or at least more open levels, but they're most likely gonna take baby steps and see what parts of the formula they can get away with. That's not saying they'll use it in the not-mania game, but it's the best step they'd take. Sega's gonna take shit slow.

Not really. Even the most liberal estimate would have a total of five games, Sonic Adventure, Sonic Adventure 2, Sonic Heroes, Shadow the Hedgehog, and Sonic '06. Out of those, Heroes and Shadow change things substantially with very major gimmicks, and those two and Sonic Adventure 2 don't have Adventure Fields. But Unleashed does, and that's clearly Modern Sonic, with Modern Sonic's Action Stage style of boosting down corridors.

So Adventure Sonic's core gameplay style has really only been done three times, with two additional games that played kinda like spinoffs. Modern Sonic has been done in four games already, Unleashed, Colors, Generations, and Lost World. Adventure Sonic hasn't really been done to death compared to Modern Sonic.

But OP seems to be talking about story and shit. The trailer for 2017 had a post apocalyptic world and shit. So it's either now or never. But there's still a good chance that they blame the story and gameplay style for Sonic '06 bombing, instead of the fact that the game was an alpha prototype that didn't even have time to dummy out unfinished elements. So if that's the case, we'll never see anything more than americanized "Sonic was never serious, guys!" games ever again.

I miss it when eggman was a serious villain and not some lame joke he is today. I mean, he held amy at gun point in SA2. It doesn't need to go as far as SA2 did, but showing eggman as more competent and willing to take risks for victory would be nice.

Ironically, at the time, people were saying the same thing you're saying now, that they missed when Eggman (but they'd get mad if you called him Eggman instead of Robotnik) was a "serious" villain, because he was never the true final boss in the Adventure-era games. That's why Iblis and Mephiles don't factor much into Sonic's story in Sonic '06, and all that stuff is in Shadow and Silver's stories instead. That was Sega trying to listen to fans and give a Sonic story that's simply about beating up Eggman. So simple, in fact, that it's about him saving a princess from Eggman. Because you want simple, right?

Then that didn't work, so they just stopped having stories entirely.

So you mean the good ones, right? Americans kept Sonic from going full furfag bullshit. That's how it got popular in the first place. You can go eat shit.

Wasn't sally created because sonic just had to have a love interest?
