I am not yet, but what I've played so far, making - as the predecessor - fun. The only drawbacks that should be mentioned in my view, are the never perfect for PC gamers and console implementation, the fact that you can not save games. This bothers me less the concept of save points - these are quite numerous and easily accessible - it's more about that later can not simply a game, for example, in ROM to load and enjoy. Although one comes back via the Animus, but is considerably more complicated.
One more word on the CE. This is really worth it. The included ART-book is just like the mini film a real enrichment and the packaging is very original. However, there was also much cheaper for pre-order. What I would recommend it to anyone friend this series, are the corresponding piggyback Guides. This convincing across the board and in addition the solution also background information and Style Work Gala Rien.
Therefore, 5 points and strong buy recommendation.
