Oh Sonic... here we go again...

[Omegajak]

The reason i like the addition of character ins the Sonic Universe validates that there's more going on here than the first games imply. Like for example: The Death Egg. NO ONE KNEW OR care about that shit?! Knuckles Presents: The Chaotix, cool Reptiles are sentient as well.

I am seriously confused as to what you mean here.

Well in Adventure we not only learn there's more humans that Doctor Eggman. We learn that he menaces them as much as he menaces others. With the improvement of technologies more beings are added to expand the fact that on this planet it's not just Sonic, Knuckles and Tails who stop Eggman from doing whatever he wants. Before I started reading the comics closely when I was younger, I genuinely believed that's all there was.
