mrkgnao: 11) The game name you post must be readily identifiable as exactly one item on GOG's current or past catalogue. For example "Witcher 2" is OK, although "Witcher 2: Assassins Of Kings, The - Enhanced Edition" is preferable. However, "Witcher 3" is not, for it may refer to any of the following four games: "Witcher 3 Wild Hunt, The", "Witcher 3: Wild Hunt, The - Expansion Pass", "Witcher 3: Wild Hunt, The - Free DLC Program", or "Witcher 3: Wild Hunt, The - Game + Expansion Pass". Obviously, "The Witcher" is even more invalid. For best results, copy-paste the name from GOG or MaGog.
