Lexor: Oh... :/
One more question then: does Galaxy needs to be "just installed" or "installed and running" for game to be "indexed"? Maybe if I do not start Galaxy together with start of whole system (I hope there is such option in Galaxy to turn if off?) then my games will not be "indexed"?
Maybe that means new Galaxy versions do not auto-add games?
As far as I'm aware it picks them up when it is started, whether it's been running or not.
I have it set not to start on start up and only run if I'm specifically going to play, update or install a game but if I've installed a game with an offline installer it's always there when I open Galaxy.
I can do some tests with some games to check and make sure if you like, but that's my experience so far.
Edit: And I suppose it's possible newer versions of Galaxy don't auto detect your games, or that I had an older version from the Beta installed or backed up which had already indexed some of them. I can't really remember now, only that I had intended to do what you want and not add my games to the client, but they ended up added anyway.
