I'll respect your opinions on the matter, but I say this as nicely as I possibly can after hearing your reasonings.
It honest to goodness just sounds like a tl;dr example of "We don't like change!"
I want some diversity in my games sometimes. I like the formula to remain similar though. Super Mario Galaxy for example. Familiar but different. Sonic 2006? I got Sonic, but it was mixed up with Silver's awesome psychic powers and Shadow fighting using Chaos energy. And of course, the game still blew as far as physics went, but the idea behind it? Awesome. I like change, with some familiarity to it.
If I wanna live in the past, I'll keep playing the old games and just ignore what's out there. If the new games are like the old? Cool. If they're new and different? Well, it's worth a shot.
See. here's the thing. You took what I said to an extreme.
You think I said, "WE DON'T LIKE CHANGE!" when I said, "We don't want too much change."
Again, if you browsed sites like Retro, you'd know this.
Retro as a collective loves Colors, loves Unleashed, loves Generation, likes Advance series; and has generally positive, but mixed reactions for SAdventure 1/2 and Rush.
Your Sonic 06 example is pretty much what i said we want (but not bad and not as radically different). The Shadow and Silver story were great concepts but I feel like they went a bit too far to make their game play different and unique, making them feel less Sonic-esque and more like tacked on gameplay modes.
Unleashed night time was super fun, but it didn't feel like a Sonic game. If they cut the stretch gimmicks, but kept the platforming, fighting, and replaced the werehog with Knuckles ie Sonic and Knuckles 2: World Adventure; the game, to me, would feel a lot more like a Sonic game.
We're not asking for the same exact thing. We're asking for different, but familar ala Mario formula. Games like New Super Mario Bros are at the core, practically the same as the NES days, while Galaxy is at the core the same as Mario 64. They also reuse characters and outside the sports games, have a relatively small cast of main characters.
Main series Sonic games didn't really do this. Adventure 1 and 2, Heroes, Shadow, 06 had many strong depatures from the Sonic formula and it's stuff like that, that was frowned upon. Addition of one-time/two-time characters were also frowned upon, since again, they werent well received personality wise.
If you look at Sonic colors, the game is amazing, but one of the reasons why is because it's familar, but different in the sense that wisps were a unique part of the game that enhanced and added to the experience without completely changing up the sonic gameplay formula. Same thing with generations. Unleashed day time stages were like this too. Sonic Rush series was also like this. Sonic Advance series was also like this. They kept the sonic formula going while adding unique things without really deviating by a large degree.
The games that did deviate weren't all bad, but they deviated hence why they're the games that were met with the most mixed reactions.
