Watch Dogs will require Ubisoft's Uplay service to play on the PC. Even if you purchase the game on Steam, you won't be able to play the upcoming blockbuster without having the Uplay client and an account. Aiden Pearce may potentially have fewer people interested in his story on PC as a result.
Despite Games For Windows Live slowly becoming a thing of the past, Ubisoft insists on using their Uplay service for Watch Dogs. Some of us had hoped that Uplay would quietly join GFWL after South Park: The Stick of Truth was released on Steam without extra hoops to jump through.
Reddit user whiterider1 noticed that the initial listing for GAME UK only mentioned Steam for on its Watch Dogs listing, giving many hope that one of the most anticipated games of the year wouldn't be subject to extra hurdles to be able to play. The listing has since been updated to acknowledge Uplay's existence, saddening many. The 6GB of RAM required for the PC report is already somewhat restrictive, but time will tell if Uplay's presence will hamper PC sales.
Watch Dogs is still on schedule to connect your world starting May 27th for PS3, PS4, Xbox One, Xbox 360, and PC. PSN and Xbox LIVE will be required, but console owners won't have to worry about Uplay. This additional bit of work to get into the game on PC might make the PlayStation releases a little more attractive with the extra hour of gameplay to boot.
