As a Greek I was waiting to play this game, after having a good experience with its predecessor, AC Origins.
I think Origins was slighly better, but maybe this is because as a Greek I may understand some historic mistakes in the game that I couldn't with the story in Origins, cause I 'm not an Egyprian. In some places they have done fantastic work, in some others hmmm not that much.
All in all, It was a great game and I would love to play an Assassins Creed with the Vikings or Medieval soldiers next time.
