Plokite_Wolf: Amazing stuff, particularly the inclusion of an SDK! Is Galaxy multiplayer compatible with Steam?
(sees username): I thought you guys vanished, happy to have been wrong!
EDIT: Seems the LAN option has been grayed out. Is this normal?
GoG does have support for allowing Steam games to use the GoG Galaxy networking to support cross-play. I will update the Steam version to support this soon.
You can use the GoG Internet Networking with players on the same LAN, however, if you want to re-enable the old DirectPlay support for LAN, you have to do that manually by editing your MajXPrefs in your My Documents/My Games/MajestyHD directory. Change the <EnableDirectPlay> field to to 1. I have this disabled by default because DirectPlay is a very old API and is not a default installation for Windows 10, it has to be specially enabled as a legacy system. Sometimes Windows will automatically prompt the user for the installation, sometimes not, and this has led to confusion and support issues.
I am also looking into why the GoG Galaxy overlay is not enabled.
