I want you to find me a list of ever Sonic The Hedgehog game ever
made. You cann take a look at http://www.sonichq.org/games/index for a
list of most of them, but it's not all. I remember lots of other,
obscure games for things like cell phones, Japanese arcades and also
other, super-rare or practically unknown Sonic games. So, I want u
guys to get me a list of ALL Sonics, categorized by country of origin
and system it's for, including the ones I already have, but I want u
to find not just a few that aren't on that list, but literally EVERY
Sonic game ever. If possible, I'd like you to find an official list
from SEGA Inc. itself, so I know that it's truly complete. I think I
got all the regular, American games. What I'm looking for now are the
Sonic games that were only released in other countries (Japan) and
weirdo, rare obscure ones that most people have never heard of, I just
want a complete list of all Sonic games, no matter of country of
origin, system, date, or level of obscurity. Even the ones for PC,
Arcade, and extinct systems like that Sega Pico and the ones you can
play on cell phones. I'm sure that, looking under Sega website, there
must be some kinda archives you could check somewhere that would have
the complete list I'm looking for, all I'm saying is, I just want to
know all of 'em! COMPLETE list.

The best official info I found is on the site for Sonic Adventure 2: Battle

(click on "view official game site")

It has a history of the game, but nothing you don't already know.

many times the brand name is licensed to a different company that
makes the actual game, especially for other platforms like cell phones
or consoles. These licenses are usually one-time-only and handled by
the marketing or legal department rather than the product manager.
What i'm getting at is that your list may not exist. It's likely that
different people, some of whom have probably changed jobs, all know
about different games and deals, and there's no overwhelming need to
compile a list with the information you are looking for. Keep looking
though and you might find it. Good luck.

I think this is the best list you'll be able to find:

Try searching "sonic" at the address listed above.

good luck,

Geez, there's still no researcher assigned to this yet? C'mon, what's
taking so long?

I just found a new sub-site at Sega.com. It's called "Sonic Central"
and it includes a list of all Sonic games.

From the Sonic Central homepage, you can click on "Sonic Games" to
browse the various games by platform. From there, you can click on
"Sonic Checklist" to download a checklist of all the games.

This seems to be a pretty comprehensive list, but I think it might
only include games released in the USA.
