Were people just hungry for a new game at the dawn of the 7th generation, or is Assassin's Creed really considered a highly regarded game ? I think it sold over 8 million combined! thats pretty impresive! Will II deliver the same results?

With the correct advertising, yes.

Although i DID see a lot of used copies like... a week after release.

Yes, i myself liked the game. And I will buy it again

Yup, it will sell even better. It fixes all the problems with the original and so will be even better than the great original, though it will lack the magic that the first had when you initially got that excitement from getting the free running going

Yes if they advertise it right.

I think not. But will sell millions.

it sure will, ac2 will be able to overtake the original easily, maybe even reached 10 million cumulatively

It will probably be pretty tough, there was a lot of hype for the original.  With a good advertising campaign it can probably do it.

I agree with what twestern...err......axumblade said

Hopefully !
