That might be changing shortly. Some information has been added to the game's page on SteamDB, or the Steam database. The game will have the Denuvo DRM, an anti-piracy feature implemented by SEGA in its PC games that causes a reduction in game performance and has received a lot of criticism from fans. The page also lists an unsubstantiated November 8th release date.
