GOG.com is offering free copies of "Realms of Arkania 1" and "2" to customers who complete a survey.

Digital retailer Good Old Games is offering free copies of turn-based role-playing titles Realms of Arkania: Blade of Destiny and Realms of Arkania 2: Star Trail to customers who complete the site's annual survey, it announced today.

The survey must be completed by September 17th at 4:59 a.m. EST in order to snag the games. Participants who already own the Realms of Arkania games have the option of gifting them to a friend.

Blade of Destiny and Star Trail were released in 1993 and 1994, and are based on the German pen-and-paper role-playing The Dark Eye games. The game follows the player-controlled protagonist on his quest to find a legendary sword and stop a coalition of orcs from wiping out humankind.
