Hey, guys! I need a list of games that use the new GOG Galaxy client. Please help me out?

The only games we know for certain that will use GOG Galaxy's features are The Witcher Adventure Game and Alien vs Predator 2000. Otherwise, we have no clue as to which games will be updated to take advantage of it.

I just hope they'll fix the problems the Galaxy features seem to be causing. Apparently, it isn't possible to utilise non-Galaxy multiplayer options (such as LAN) with the GOG version of AvP. That's not cool in my book and also runs contrary to GOG's mission statement that Galaxy is supposed to be a purely optional client.

My copy of Terraria has a Galaxy launcher with it, so that too, I suppose.

That has nothing to do with Galaxy. For some reason the initial AvP Classic 2000 release on Steam had no multiplayer at all and eventually Steamworks multiplayer was added (and now obviously Galaxy as an alternative on GOG). I have no idea why Rebellion was unable to release AvP Classic with LAN play to begin with but obviously that has nothing to do with Galaxy.

Actually, AvP's multiplayer is P2P, so LAN should be trivial. The only hitch is, the current GOG build requires you log in through the account for MP. You can't even change your in-game name, it uses your GOG nick. So yes, it has everything to do with Galaxy functionality. If they restore some of that functionality (private games, player profiles), LAN is practically built-in!

Unfortunately, since GOG has released AvP for sale, they must consider it full-featured, and therefore won't bother changing any of that.

Back to OP, wasn't Divinity: OS supposed to have Galaxy functionality?

Nope, it has everything to do with Rebellion being for some reason too lazy to include LAN play. It was true in case of the Steam release, it's true here. Even if GOG never encouraged Rebellion to include LAN play, I'm 100% certain that they never said "yo, only include Galaxy, no LAN play, capisce?!".

Oh, I see; I didn't know this was already an issue to begin with. Thank you for the correction, I appreciate it.

You know, despite downvoting the op, we ARE going to need a definitive list of installers that come with Galaxy. I assume once Galaxy is live no new games will come without. There won't be Galaxy free installers provided, so this "wholly optional" thing doesn't really inspire me with confidence.

I was arguing the technical side. GOG have clearly had some access to the game's net-code and have gated it through Galaxy. Maybe Rebellion explicitly forbade them to include LAN functionality, though seeing how limited the existing functionality is, I'm inclined to ascribe it to unwillingness or disinterest. It's DRM by apathy, at best. At this point, the Steam release is actually, functionally better!

I'm pretty sure they've already stated that "{Galaxy free" installers *would* be provided...

That would be a start in my mental recovery from being blocked from my game (in single-player, offline) this weekend. Thanks...

Found a reference:

Judas states: "you'll always have the option to get a standalone installer and any patches that come with it as always"

What makes you think that? Did GOG elaborate on their cooperation with Rebellion concerning Galaxy support in AvP? Because the last thing that should be necessary in case of a multiplayer API like Galaxy is to have the developers of the API actually mess with the games themselves. I can imagine that GOG studied AvP's multiplayer component a bit to optimize Galaxy but I have serious doubts that they themselves actually did any of the implementation. I was sure that the whole practice of delivering Galaxy via the game installers is just a temporary solution until the actual Galaxy release.
Yeah, well, he also betrayed Jesus...

But I'm sure we can trust him on this one.

But he was well paid... can you blame him? ;)
