Before buying I was still a bit skeptical about the exaggerated copy referred to in the media, with a permanent online connection is really necessary. But even this has now been loosened again, so you can install the game with a clear conscience. Before it can go off, you have to before installing an online account at Ubisoft build, but this is primarily used only for verifying the authenticity of the game and the online storage. Surely there are other ways than the online Score storage, but in the end it is nothing more than with the current STEAM Shooter 'CoD Black Ops'. There, too, the score will be stored online and not paged to your hard drive. That should not deter you from buying one of the game Assassins Creed 2.
A little tip:
For those who do decide to to add itself the game, it would be advisable to before the game even to take half an hour and the short film 'Assassin's Creed Lineage' to look at YouTube. Then a shot of the game while the individual missions with an entirely different perspective.
Conclusion:
For those who are still undecided, yet the game play with the idea to buy, which I can really recommend it. You will not regret it. Also, I am sure that all who have played this part, then sit down with the idea apart, in addition retrospectively 'Assassin's Creed Brotherhood' zuzulegen. Personally, I'm going to do with security.
But now a lot of fun in Assassins Creed 2 ;-)
