When R.U.S.E. is released in September, it will benefit from Valve’s Steamworks API to offer the best community experience to players. Consequently, a Steam account and Internet connection will be required to activate the game, as per Steam policy. For this reason, R.U.S.E. will not use the Ubisoft protection. Single player can be played offline.
This makes me inclined to purchase R.U.S.E. just to show Ubisoft that I support this decision. If they're releasing a game on Steam, why require two DRM methods? Hopefully this signals the beginning of the end of their DRM methods of the recent past.
