-Instead of being a Sonic clone, Knuckles got to treasure hunt.
-E-102 shooting stages.
-Team mechanic in Sonic Heroes.
-More focus on story.
-Offering more than one viewpoint on the story.
You're right. These ideas were so innovative. Treasure hunting with Knuckles? Well, I haven't seen that in a million other games. Imagine, collecting things in a videogame! How innovative!
The E-102 shooting stages weren't innovative either... they felt like the obligatory shooting levels tossed in at the last little bit to try to add some variety. They too suffered from a bad camera, which is unfortunate, because they probably would've been fun if the camera hadn't got in the way all the time.
The Team mechanic, seeing as how it was taken from a previous Sonic game anyway, certainly was not innovative.
As for more than one viewpoint... it's been done in others games plenty too. Some of the different characters were fun, but nobody living or dead has ever wanted to play as Big the Cat.
They're absolutely not synonymous. Granted, Sonic is a well-known video game character, but Sega has many other talented development teams that have made their mark, the most prevalent one being AM2, for their Virtua franchise. See also Overworks for Sakura Taisen and Skies of Arcadia, Hitmaker for Crazy Taxi, and Smilebit for Jet Set Radio.
Of course there have been other development to make their mark, and they have made great games, but saying that Sonic (direct product of ST) isn't synonymous with Sega is like saying that Mario isn't synonymous with Nintendo.
Who are you kidding? First, just because it would be 2D wouldn't mean it would play well (just look at the GBA Sonic games). Secondly, Sonic Adventure was and probably still is the best sold Dreamcast title. It was quite popular and critically acclaimed, despite its shortcomings.
I'm not saying that 2D makes the gameplay good, but the greatest thing about the 2D Sonic games was the gameplay. If the 3D Sonic games had possessed the fluidity and solid gameplay of the 2D Sonics, then perhaps it would've played better.
As for Sonic Adventure being popular, I think that it was mainly because people were just happy to play a real 3D Sonic game. And back then, it was pretty cool. However, when we look back, we can start to see the sloppiness of Sega and Sonic Team, which is clearer in light of the games made since Sonic Adventure.
You would have preferred a cookie-cutter story? The game was unique in that it was very consistent in having six characters with their own roles in the story that you could play.
The story was pretty close to cookie-cutter. It was filled with an unbelievable amount of clichés. Six players was nice, but it's not like it's a new concept... branching story lines have been around for quite a while.
That's quite a simplistic view. They tightened the controls, made the game more action-packed, and threw in a Light/Dark theme. The Sonic/Shadow stages were especially good.
The controls didn't strike me as too much better, but that's my opinion. As for throwing in a Light/Dark theme, that's got to be one of the most clichéd plot devices ever. Like I said, "dark" anti-hero to try to make the game more appealing.
And why not? You seem to be okay with other franchises and Sonic games repeating the same concept. In this case, they fleshed it out a bit.
Just because I expect the same level of quality out of the new Sonic games as did of the old ones does not mean I want the same concept. They are two very different things. The old games might've had a few problems, like most games, but they were never what I would consider to be "sloppy". Unfortunately, the new Sonic games, and a lot of Sega games nowadays are sloppy.
