I stand my 123 on this. Sonic 1 only shows Sonic.

Some fans still call them "Mobians" purely as a racial name for character design to distinguish them from usual anthros in art and design. I myself mostly call them "Sonic characters" or "Sonic fan characters" but it's just easy to sum them up with the name "Mobian".

All in all the entire main series of Sonic games take place on Earth since Sonic 1. Sure only Sonic, Dr. Eggman and little animals were shown as the only inhabitants of South Island and West Side Island but these islands had urban zones with cities in the background, well we can pressume island residence consist mostly or entirely of mobians/Sonic's multi-animal race/anthros but presumption does not mean fact. A number or just humans could live there, it's never confirmed because Sega at the time didn't see the point in wasting 32-bit limits with unneccisary background NPCs.

I also believe that Sonic Adventure to most modern games takes place on the mainlands which is why humans are introduced. This is because the consoles now have more processing power to spend on NPCs. Another presumption could be Sonic's World (Earth) consist mostly of humans while mobians prefer island habitats or live in secluded areas. The evidence to support this is how most NPCs in Dreamcast-Modern Sonic games are humans while Classic Sonic games mostly take place on islands.

If you still think I am bull$#!77ing and point out how I call Sonic's world "Earth" while it is nothing like our own planet, thats another thing entirely involving alternate timeline of our very planet and all that. I'll post a forum link once I find it.
