CasualKiller: The patch violates GoG's policies, as it incorporates content that can only be obtained by registering online on a website.
It's called PlayFab, and it's a nasty piece of spyware.
To promote it, users are also being tricked into joining the "Society of Raiders", in a way that forces them to give up their cell phone info.
..and if that wasn't bad enough in itself, this malware has caused a lot of problems for the Steam versions, like hangs, freezes, broken saves, and completely preventing the games from even launching!
As a workaround, all of the reported issues are apparently fixes by manually removing the PlayFab files from the game directories.
However, this is definitely not something that we want to have in the GOG versions, so I'm glad that the patches have been delayed, if it means that we evenually can have them without PlayFab!
