I didn't say you had to completely reinvent the wheel with every single game. It's entirely possible to reiterate on the ideas that came before in creative new ways.
Classic ideas can and still do work in the modern market. The success of Activision's remakes prove that. But I would rather see a whole new Crash Bandicoot game with the aesthetic and controls of the remake, instead of just bringing back the experiences that we had before.
Similarly, an entirely brand new 2D Sonic with nothing but new levels would be far more preferable to the mix-and-match nature of Sonic Mania. Something new and fresh and different and exciting.
That isn't "making entirely new foods for every meal". You're just using the food you have in creative new ways.
I'll try new food over the same cheeseburger and fries any day, mind you. But people like their comfort foods, I guess.
