I havent bought it, but on the demo it has 'multiplayer' as a option....i take it that must be 2 players on the same console then?

Yeah. The only options in Multiplayer are:

Local Co-Op

Local Versus

and Xbox Live Versus

 

Well, my purchase wasn't in vain as I did get the full 12 achievements and 200 Gamerscore unlocked. So I'm at least happy there.

I kept tellin people it didn't have it, and no one listened. Go fig.

 

No surprise, but that really sucks for people who bought the game for that reason.

Those checklists on xbox.com (and even other sites like TXB and IGN) have been so full of misinformation in the past that I don't even look at them anymore. I try to steer people away from relying on those whenever possible.

Unfortunately for retail games relying on that checklist when you pickup a game at release is the only real option. I am pretty sure the checklists are created before going gold since the mislablings are generally a reduction of online max players or revolve around features cut before release.

Good idea, but poor execution. Made even worse by the inability to return opened or downloaded software. Buyer beware is one thing but misinformation is another.

I am someone that did buy this, as did a couple other friends, because it was advertised as being multiplayer co-op online as opposed to just versus. If I had known it wouldn't have this feature I would have totally passed on it seeing as to how I havent finished Sonic 1 yet, and have a crap-ton of other games to play too. I emailed MS about it complaining because this is technically false advertisement, and personally I won't have a problem taking it to someone else if they won't even partially reimburse me or something.

crap-ton is my word of the day...a perfect way to describe my backlog of games too...and this holiday is going to be MURDER...starting in 11 days.
