I love this game, but a word of caution: You will not be able to copy you saved data.

I replaced my hard drive this weekend (went from 40GB to 320GB). I was backing up all my game saves, but when I tried to do AC2, it wouldn't let me. Only game I have that has done that.

What's bad about it for me was the fact that I was 60% finished thru the game. So I'm gonna have to start all over on the new drive.

Fortunately I won't lose my trophies: those were synched up with the server.

So if you buy Assassin's Creed II, remember: the saved game is locked and cannot be copied.

I'm gonna try and see if there's a workaround with Ubisoft. If there is, I'll let you know.

i was gana upgrade my hdd also, and i was going to get acII

i had a few other games i couldn't backup my games to :\
I just put them on my magic memstick, but there were some i couldn't do, I think Monsters was one of them..
