Hi.
Why in manual of Risen 2 game on GOG are information about the need to have an account and the Steam client? I know that Risen 2 has been moved to the DRM-free version from Steam and the manual is a scan from Steamworks Edition, but IMO this kind of error should be corrected.
Regards

P.S. Sorry for my english.

Not sure, but probably because it's the only version available?
If you want, you can contact support.

Yes. All versions of the game (except the one from GOG.com) require Steam.
I think that if they want (Deep Silver or Piranha Bytes) distribute DRM-Free version, publisher / developer should prepare a correct manual.

P.S. How can I contact with GOG's support?

Ok. I wrote. Thanks.
P.S. Do you know how much time they need to answer?

That's individual, from couple of hours to few days, depends on the issue. As this one is not so "urgent", don't expect quick reply. ;)
