BKGaming: It really could be a number of things such as adding cloud saves, the overlay, or just general fixes related to Galaxy.
groze: I thought it could be any number of those. It was a *big* number of games being updated, definitely more than a dozen. I didn't write down all of the updated games (I know I should have, but I'm disorganized and lazy like that, hence why I use Galaxy in the first place), but I remember what some of them were, and I know a few of those still don't support either cloud saves and/or the overlay. Which leaves out general fixes related to Galaxy.
I'd still like to know what, exactly, was updated, though, but I guess that's not likely to happen unless some blue in the know decides to chime in.
to be honest I am not sure what happened myself. You are right that those games didn't receive updates for a long while. Would you be willing to send us logs to galaxy-client-support@gog.com, so we can check what kind of updates Galaxy performed?
