Frogwares claims their publisher, Nacon, pirated their game - Polygon

More recently, Parisian company Nacon rebutted by telling fans that the Steam version was “official and complete.” But now, Frogware has new allegations: As the studio tells it, Nacon hacked and sold The Sinking City in order to list it on Steam.

On March 1, Frogwares clarified the original claim in a very technical post that illustrates why the team thinks Nacon hacked and pirated its game.

In addition, according to the Frogwares post, “[Nacon’s] version deleted all the achievements we prepared, thus removing a key feature of the Steam community.”.
