I have Assassins Creed 2 on the PS3 and finished it last night (the regular missions). Its a great game (I did use the strategy guide ). I am at 95% total completion and have 92% of the trophies.

The story is interesting and I plan on going through the first Assassins Creed on the PC. I also have Assassins Creed Bloodlines on the PSP.

However one minor blemish on the game involves the ending. I won't say anything for those who haven't finished it yet. But I will say it is factually incorrect. What they allude to in the voice overs during the credits is not entirely accurate. Do a google search for the discussion they bring up and there is more detail available (in fact I've seen documentaries about it). Again I won't get into detail to save the spoilers for what they are trying to setup for Assassins Creed 3. Just thought I'd through that out there.

Oh by the way I had bought the standard version for the PS3 on disc but downloaded the 12 and 13 sequences. I did finish those in order before starting 14.
