I use it sometimes for some games. No rhyme or reason, really.

I'm just using it for cloud saves now.

Do you have it on your PC? The achievements might have been read from save game files.

yes I like it

I don't give a flying fuck about "cloud clients", so I won't use Galaxy, like, ever. Just to give you an idea: I installed Steam just recently to play one of my few original, Steam-based games on DVD (Portal 2), and I had to ask Valve to recover my account which was created in December 2004 to play Half-Life 2 on a Pentium 4 and never used again.

Clients are a fucking annoyance. I just want to play my game.

No. I really don't see the benefit.

Never have.
Never will.

Oddly, one positive about GOG ignoring Linux is that hopefully this abomination will keep getting delayed for Linux as well.
