In the first day of its release, Watch Dogs sold more copies than any other Ubisoft game ever. It even broke record set by Assassins Creed, a game has since spawned numerous sequels and that Watch Dogs developers had a bit of friendly competition with. The team behind the game was very grateful for the record breaking sales, which came in spite of some issues that Ubisoft games are experiencing on Xbox. Microsoft issued an Xbox Live service alert today, telling gamers that they are working to resolve connectivity issues on Xbox 360 and Xbox One for Ubisoft games. The issue causes difficulty when joining other Xbox Live users in online games, managing friend lists, and tracking friends games.
