HOLY.SHIT!!! I'm at sequence 3 and already this game has become one of my favorite games this year, perhaps THE Game of the year.
This game is awesome beyond words, they've improved it quiet significantly. The facial animations are a lot different then in AC2 and AC1. Desmond, Lucy, Ezio look so different and soooo much better! Even the graphics look better then AC2's and show some improvement. Rome is down-right beautiful. Desmond's new attire is a lot like Cole from inFamous and Faith from Mirror's Edge and he also talks a lot like Drake from Uncharted does (same voice actor along with the same smart ass way of talking).
And the battle system is just as good as before with many great improvements but the main feature of all is, YOU CAN FUCKING CHAIN KILLS TOGETHER. Suppose you kill one guy and then you automatically attack in another guy, Ezio kills him and then you attack another and so on so forth. But ofcourse if you get hit the chain is broken and this usually works on the more weaker opponents, a more armored soldier usually blocks more.
You can ride your horse in Rome and you can also call for your horse which is extremely necessasy is Rome is damn huge and u can't get to a place just by walking to it. This game also has a much better economy system in which instead of just buying, you can also collect stuff in chests such as incense, rabbits foot etc. and which you can later sell at shops for profit. You can also renovate certain shops which increases the amount of income you get per 20 minutes. Also sometimes you can't renovate shops in certain places since they're in influence of "Borgia Towers" and to get through it all you need to kill the guard in charge of the Tower and burn it to hell. They've also added a Virtual Training mode in which you can complete certain challenges and gain medals depending on their requirements and you can also do certain 'Guild Challenges' such as (Thieves Guild etc.) which are certain things you have to do depending on the requirements and if you succeed you get more florins and gain the guilds trust.
Also in most missions there are requirements for attaining "100% syncing" such as make it through this memory without getting hurt or within a certain time line etc. You can replay memories, you can leave the Animus at any time, you can do ANYTHING
. I haven't got my assassin bro's yet just waiting to get them, can't wait to B.A.M them all. And yes again you have to uncover THE TRUTH.
Still so much I haven't mentioned and so much I've still yet to experience, hell I haven't even tried the multiplayer, but this goes without saying, this is a MUST play.
