Fighters. Even though Metal Sonic is cheaper than my dad. And that's saying something.
I vote for sonic 3D!
3D
Sonic the Fighters FTW, yo!
Why? Because of it's supporting cast! =O Nak, Espio, Bean and Bark, just to name a few.
Hmm, never played Fighters, but it looks such great fun! And it has Bean! The Duck! Plus it has awesome music.
So, Fighters.
Sonic the Fighters was good...but there are a LOT of better Fihting games out there IMO.
Sonic 3D works as a good game in itself, even apart from the Sonic franchise, plus the Music was awesomely ambient (Diamond Dust Zone had an awesome tune!)
So...
SONIC 3D GETS MY VOTE
(Ha ha, I knew Sonic Labyrinth would get pwned...ho ho)
Hmm....Sonic the Fighter gets my vote, but it is a tough choice, I do enjoy Sonic 3D quite a bit.
oh no!
gotta go with 3D
it worked as a sonic game and it worked as a semi-sequal to flicky. the soundtrack for both the genesis and saturn versions were different from each other but both great.
trippy special stages on the genesis and classic on the saturn.
great game and tragicly underrated.
fighters is fun but it's novelty wears thin after a while
^ Amen to the above!
Weeeeell, 3D wins!
SAFE GAMES: Sonic, Sonic 2, Sonic CD, Sonic Chaos, Mean Bean, Sonic 3, S&K, Triple Trouble, Chaotix, Tails Adventures, 3D Blast
Next games:
Sonic 3D Blast: Flickie's Island (Saturn)
Sonic Blast (Gamegear; aka G-Sonic)
3D again gets my vote.
pffft 3D again
Sonic Blast! Because I played it so much as a child and it has that nostalgia thing to it.
Besides, I've never played the Saturn version of 3D Blast. 😛
I don't see what the point is in differentiating the two 3Ds o.o
You might as well do every single different version of Sonic 1 that's out. Like those Sega Smash Paks or Sonic Jam or whatever. It's pointless 
3d, because I can't stand G-Sonic :/
sonic blast fun but I liked 3d blast more so my vote is for
3d
I really didn't like either one, but since I've ALMOST beaten Sonic 3-D (Stupid final boss was undefeatable!) I'd have to go with that one.
Definitely 3D for the Saturn. The Game Gear Sonic Blast gave me a headache. I never played it again after I beat it.
Different music, graphics, and special stages from the Genesis/MD version - it's a different enough game for me. Whereas all the different versions of, say, Sonic 1 or Sonic Spinball are all pretty much identical.
And on that note, 3D wins!

Next:
Sonic R
Sonic Pocket Adventure
As much as I love R, Pocket Adventure is just a great homage to the classic 2D games, so that's got my vote.
SONIC R! SONIC R!!!
One of my top favorite Sonic games of all time.
Loved it so much...all the nostalgia..
R was fun but Pocket was a great little mishmash of goodness
Pocket vote get!
ive never played pocket,anyways sonic r was great; its still one of my favorites.
Sonic R is a classic. (my vote)
Sonic Pocket Adventure is something I must've missed out on.
I love Sonic R. Every time I'd play I'd just race thru and get everything, and then start over. ^^
R gets my vote without a doubt.
Sonic R > Sonic Pocket Adventure, yo.
R wins!

Sonic Adventure
Sonic Shuffle
SA, without a doubt.
I was there on 9-9-99 picking up my Dreamcast and SA. I couldn't believe what I was playing, it was so awesome.
Sonic Adventure is da winna
XD *Almost dies laughing*
Sonic Adventure!
Sonic Adventure! I waited 6 years to get to play it and now I have DX. x3
Sonic Adventure. The reason I bought a Dreamcast, one of the many reasons that I still play my Dreamcast. 
Okay, I take back what I said earlier, Sonic Labyrinth has graduated to the status of "The worst Sonic Game ever made-except for Sonic Shuffle"
If you get what I mean...
I'll write this one in photoshop...
IN OTHER WORDS...
Sonic Adventure gets my vote 100%, no doubt about it
I love sonic adventure, I still hook up my dc every few months to play it.
my vote is for sonic adventure. probably the easiest choice to make so far. Instead of shuffle for a choice it should have been sonic adventure 2. Then I would have a hard time deciding.
I vote Sonic Adventure. Adventure had more of a plot, which I like.
Adventure wins, there is no doubt.
Just kidding. SONIC ADVENTURE.
And, personally, I'd rather play Labyrinth then Shadow the Hedgehog.
Wow...that's not very fair.
I actually enjoyed Sonic Shuffle...but of course I loved Sonic Adventure better. I even orded Sonic Adventure DX for PC on Ebay the other day! Can't wait for it too X3
Shuffle is one of those retarded games that I hold dear to me...
but Sonic Adventure is just WAY too epic.
SA, unexpectedly, wins!

Nextish:
Sonic Adventure 2 (Battle)
Sonic Advance
go, SA2!
hmm... neither is my favorite but i guess ill go with SA2 (battle or other wise)
Hmm, this'll be a close one ... or maybe not.
I'm voting for Sonic Advance mainly because of its homage to the classics. I really liked the style of the game -- I regret selling my GBA.
Sa2. Sonic Advance just had TOO many flaws =_=
Plus Sa2 has Shadow.
The end.
Hmm....tough one...I love playing Sonic Advance with Sonic and Amy...and I love Sonic's levels in SA2....Sonic Advance also had some classic level and boss themes also...but SA2 had Deem Bristow which means I vote Sonic Adventure 2.
Hmm...This is a CLOSE ONE, Sonic Advance reminds me of the good old Sonic 3 days, especially Angel Island zone (reminds me of Marble Garden crossed with Sky Sanctury).
No...no...Sonic Adventure 2 is the superior game I'm afraid, the Multiplayer mode of Battle, and the Chao Gardens makes this a Winner.
Whilst I don't think it's as good as Sonic Adventure, it's still one of the Top games.
SONIC ADVENTURE 2 GETS MY VOTE!
(btw, sorry for being so mean to Shuffle last time, I don't really hate it as much as I made out, it's not as great as Sonic Adventure, but at the end of the day, it's Sonic, so I gotta love it.)
sonic adventure 2 was great
so my vote is for sonic adventure 2
SA2 wins!

Sonic Pinball Party
Advance 2 ftw!
Sonic Advance 2.
Even with it's faults, it's still more enjoyable.
That said, Pinball Party's soundtrack is fun to listen too. ^^
I vote sonic advance 2, it was kind of fun but better than sonic pinball party
I'd have to vote Sonic Advance 2, because I never actually played Pinball Party.
Pinball party was actually a well executed pinball game. I wasted many hours with it. It had a NiGHTS table AND it didn't make me as angry and "again?" Advance 2 did... therefore Pinball for me
Advance 2. I just liked it more than pinball party.
Sonic Advance 2. I didn't even know there was another pinball game.
Advance 2 wins!
