whystler2012: Interestingly, as much as it is lacking core GoG functionality compared to the previous launcher, it's Steam integration is quite good. It shows me significantly more information available through the Steam API that the Steam client itself for some reason is incapable of providing, like which of my games would run in Linux/SteamOS without having to actually start the Steam client on Linux itself. It also shows, for some games at least, what level/subgame/zone within a game people on my contact list are at, whereas the Steam client just shows the game they are playing.
My friend list (the new one) still shows the areas in games that friends are in when they're playing.
Ability to view linux and SteamOS compatibility on Windows was available in older versions of the Steam library, but is one of many notably-absent features with the updated client (which is also causing medical problems for a number of users with Valve having known about the problem for at least 6 months and refused to deal with it).
So yeah, GOG Galaxy 2.0 is an objectively better Steam than Steam is, but an objectively worse GOG Galaxy than 1.2 was... Good job, GOG...
