South Park: The Stick of Truth doesn't require or even use Uplay in any way. The news comes from developer Obsidian, who took to its Twitter account to confirm the PC version is a Steam game, and a Steam game only.
As AusGamers notes, The Stick of Truth was a THQ game in a past life, so perhaps that's why it's not integrated with Ubisoft's distribution and DRM service. Obisidian didn't offer an explanation in its answers to fans' questions.
Whether or not the news leaves you happier than a poop at Christmas, the game is less than a month out. The Stick of Truth thwacks North America on March 4, Europe March 6.
