That's great news, indeed! While I didn't always consider myself a big Assassin's Creed fan, after a friend and I played through a majority of Assassin's Creed II one night, I realized how interesting of a series it really was. While I always knew it was a good series, it didn't always seem right for me. That partially had to due with some real life issues going on with me during that time, though.
Originally I was worried that a third installment to this exciting series would project a nearly identical experience to Assassin's Creed II, being the beginning of another repetitious series. From the description on the back cover, however, it seems that they are taking a new approach to the game, making you a leader of a sort, which is great. I think, considering the quality of the series, they will really make great use out of the new circumstances of which the game is to have. I can't see them completely ruining this concept of you being somewhat a leader of a group of assassins.
Also, it'll be very interesting to see how they set up the multiplayer mode. I have utmost confidence in Ubisoft to do it well, but it's something that is hard for me to imagine.
Great work as usual, Caspa.
