alt3rn1ty: Edit : Ooh yeah, forgot to mention, if you dont have GOG Galaxy installed, you will hobble most multiplayer functionality, but if you are happy with it just as a single player game thats no problem.
ewhac: Define "installed." I have a (fairly old) copy of Galaxy
installed -- because some games crash if the Galaxy DLL is missing -- but it never gets run.
"Define installed"
Installed does not equal not installed
I do not have an extensive list of games from GOG - Currently only 4 titles - But I have found with every one of them if you do not have GOG Galaxy installed at all, and you only use the Offline Backup Game Installers, they all work perfectly fine without any galaxy related files.
GOG used to provide only Individual Game Installers, GOG Galaxy is a new thing that GOG obviously wants to push us into using ( hence why they now bury the Offline Backup Installers and you have to find them underneath the huge INSTALL WITH GOG GALAXY button :D )
If GOG are now making games dependant upon having Galaxy files installed, something is going seriously wrong somewhere, and I would complain about it. Everything here is supposed to be DRM free and not require any clients like Galaxy.
-------------
Note things can get confused if you have previously used one method. Say if you have used an Offline installer for a game, Galaxy not installed. Then you install Galaxy without uninstalling that game, Galaxy will then take over managing the games it finds on your system from GOG, updating them etc etc.
So if you want to switch between the methods, to be sure nothing goes wrong you really ought to fully uninstall the previous game installations and or GOG Galaxy, before changing over to managing your games manually or automatically without or with Galaxy.
I use Offline Backup installers - If I want to switch to beta versions of a game I need Galaxy, so then I would uninstall the Offline Backup version of the game, then install Galaxy, then install the beta version of the game I want to test. Afterwards, I would uninstall the game via Galaxy, then uninstall Galaxy, then re-install the game from its Offline Backup Installer ensuring there is no confusion as to how it was installed and its dependancies.
Times that procedure by however many games you have installed could be a PITA
Maybe you have a game or two that have a confused installation which have somehow become dependant on this galaxy.dll ? .. Whereas if you had installed the games purely with the Offline Backup Installers, without Galaxy ever having been installed (or subsequently installed after the initial installation), then the games would not be looking for this galaxy .dll
Never had that issue personally.
