This weekend, the all games of the Risen series are available on for a reduced price. If you'd like to get a copy of the game free of DRM or any other copy protection, maybe you should take a look.

For instance, the "Risen 3 Titan Lords - Complete Edition" makes its debut on GOG with a 50% discount, or just below 15 Euro total. The Gold Edition of "Risen 2 Dark Waters" is priced at 5,39 Euro and Risen 1 is up for grabs at just 1,79.
