Assassins Creed 2 is not that hard if you played the first one. it can be hard to understand the games storyline. I completed the game in about 4 days with a lot of hours playing it some guards you have to fight makes the game harder but when you move on the game it gets easier. So personally I don't think the game is that hard but very very fun.
You cant on AC2, but when Assassins Creed Brotherhood is released, you can then. :)
no it does not have online play
Yes, if u don't beat assassins creed 2 then you will be totally lost when you play assassins creed brotherhood. because it starts off exactly where it ended and you'll be sooo confused of who everyone is how this all started what happened I HIGHLY recommended you play assassins creed 2 before you play assassins creed brotherhood. :)))
For Assassins Creed 1 No, for Assassins Creed 2 yes.
No, but I would suggest playing AC2 before playing AC Brotherhood if you care about the plotline.
You dont
assassins creed 2 has definatly a larger map but the kill streaks are much better on assassins creed brotherhood but the story line is alot better in assassins creed 2 hope you have fun with assassins creed 2 or brotherhood ;)
