deejrandom: Did PB not develop Gothic 2?
PB made the first three Gothic games (including the Gothic II expansion Night of the Raven), but everything after that is not developed or endorsed by them in any way. Their previous publisher, Jowood, maintains certain undisclosed rights to the Gothic brand, and they have taken advantage of this to make the abysmal Gothic 3: Forsaken Gods as well as the upcoming Arcania: A Gothic Tale (Gothic 4).
SilentChe: I probably wont get it unless its a downloadable DRM-free version. After GOG started providing games like that, I kind of dont want games any other way ;)
The DVD release only uses a simple disc check. This check is powered by Tages and requires a driver to be installed but it's so basic that the pirate releases didn't even need cracks (it will accept a mounted image as the real thing without even needing virtual drive cloaking or the like).
Stay well away from the Steam release. It uses a fuller version of Tages that
requires a serial and online activation(!) for some bizarre reason. I'm not sure what is used for the Direct2Drive and Risen Store releases, but beware. If you don't mind mounting your own image the retail version would probably be the closest you could get to a DRM-free, disc-free experience.
