Summary: As with many other people who purchased this product, the Assassin's Creed II CD gave me an error saying that the file was corrupt. I contacted support for both encore and ubisoft. Encore support replied that I needed to contact ubisoft. Ubisoft support took about 3 days to respond (much too long in my opinion) and sent me a regurgitated message recommending that I try a bunch of things first and reply back to them with a bunch of information.
Summary: I like Assassin's creed but when i wanted to continue the story, Assassin's creed 2 disk was unreadable. I thought this was weird because I installed a lot of games and they installed fine and this was new with no marks or scratches. So i paid 10 dollars for Assassins's creed and a copy of Assassin's Creed 2 that is unplayable. I've check online for a solution and none of them worked. This is just my luck.
Summary: AC1 installed and played just fine, love the game. AC2 refused to install, said I have the wrong version of windows. Win7 64bit. I asked customer service what the deal was and they told me to register online and download the game with their Uplay client. My internet bandwidth won't allow a 6+Gig download without multiple errors. Why can't they just supply a disk that works?
Summary: Strong Plus: the climbing--it really adds another dimension over what most video games use, so that's a fun, different adventure. Negative: The story feels short by modern standards, and there's basically no development at all for the metanarrative (what takes place in the present), so it's really unclear why it's there at all. The fighting interface is good enough, but fights get repetitive quickly. Assassination variation can be okay.
Summary: Neither of the discs are reliable. When they are recognized by the drive the install fails with a cyclic redundancy error. This is evidently a known and long-standing problem with this release. Why it has not been removed from the shelves and corrected I can't say but it is certainly a black mark against Encore and Amazon. I have tried contacting Encore's customer service but so far (several days) there has been no response.
Summary: The game was nice, and I enjoy playing it. If you never play AS1, you will have some trouble catching up the story. The download system was kind of suck. The server connection was not sable, and resulted in installation error. I downloaded for about 6 times to finally get it work.
