In what appears to be a common trend, the PC version of a game is being released sometime after the console version. This is fine as long as the port is done correctly (I'm looking at your Arkham City). Ubisoft have announced that Assassins Creed 3 will be released on November 20, almost a full month after the October 30 release date for PS3 and 360.
However, it will be released with Ubisoft's DRM, which, as you know was found to contain a rootkit. This will put a lot of people off (myself included) which is a shame because the franchise is a lot of fun! Let's hope they at least learn from the mistakes made with Batman: Arkham City and actually test it on a PC before they release it!
