Think about it maybe the first or 2nd time they do it, it may be fun but after that we would get all bored. why do you think they stopped making the classic and pixilated only games and started making the more 3-D games that you can actually move around in, and then both mixed together (minus the pixilated part) that is why we do not see silver sonic, classic amy, or any of those mostly old characters, but if you ask "Then why didnt they remove sonic, tails, knuckles, or amy?" it is because they are the 4 main characters.

Actually, the reason the game styles changed was because of advancements in technology, and decisions later made on combining the older gameplay styles with modern looks for some games. Most of the original characters were modernized along with the game styles. I would assume that they didn't modernize a few of the older characters because they weren't as popular or important in the story as the other characters.

And yes you're right- they obviously didn't remove Sonic, Tails, Knuckles or Amy because they are the main characters and they had future potential.
