In my opinion, this is the best game I've ever played. And I'm old school.. I played original Tomb Raider and all that stuff. This game has the right mix of adventure, assassination, storyline, monsters, battles, and everything. I played from both points of view, once as Kassandra and the other as Alexios. Some of the storylines are a little much, as far as overt sexuality goes, but to some that may be a plus. Lol! Of course, there is the little matter of more than 500 side missions. You could lose yourself trying to get them all done, and the synchrony birds are numerous, but worth it. That little bird kicks ass, too.
I just love this game and I'm actually playing it again. Sometimes you can never get enough of a good thing!
