Adding my voice to this chorus of lovers of ACR. It's not perfect, but no game is. I was frustrated by Den Defense at first, because it is a rather steep learning curve, but once I figured it out, I managed to squeak out a few wins. I like the back-and-forth between the Templars and the Assassins here--it makes the struggle between them seem real. This is most evident in the Mediterranean Defense game. As I write this, Algiers is under Templar attack, and I need to send a squad to boot them out again.
Like the bombs and the hookblade. Hookblade was a great improvement to navigation, and helped balance Ezio's advancing age. Believe me, I noticed. Bombs are just too much fun, especially when I can make Janissaries magically sprout gold coins. That, and I'm a fan of Jeff Dunham, so the bombs make me incredibly happy. *unrelated, I know*
Music was awesome, but then it always is. Loved the new characters, especially Yusuf () and Sofia. And I like what they did with Ezio, too--I got the feeling that he was sick and tired of dealing with the Templars at every turn by the time the game was done. In his boots, I probably would have done the same thing. Altair sequences were a little short, but they really fleshed out his character. I just wish I had an opportunity to jump into some water just to see what would happen.
Multiplayer is better this time around, too. I'm still plugging away at Brotherhood's MP, and I'm continually getting frustrated by being placed in matches with people whose levels are way above mine. *level 11 noob* Makes advancing really difficult. Addition of a gameplay mode where it's just you and your opponents, no abilities and no compass... I love it. I feel like I can get a foot up now. So far, haven't had any problems getting into matches. *knock on wood* Overall, enjoyable game, and I loved it. Hoping for some single-player DLC soon!
