jhkrischel: To be clear, I've got no problem with a game seeking connections to update achievements - the problem is I'm detecting the game running a server *waiting* for connections on port 9264.
Now, yes, I have a NAT, and I'm not port forwarding 9264, so it's not like having a server listening there is a complete breach of my defenses. But if I'm running the game on a network that isn't so secure, and some random person scanning ports finds I'm listening on 9264, what will they be able to do? Will they be able to access information about the game? Other parts of my computer?
If I'm running a multiplayer server where people need to connect, I get it, I need to be listening on a port to get their requests. But a single player game, regardless of what kind of GOG Galaxy integrations they have, doesn't seem to have any valid reason for listening on an open port for incoming connections from random people.
It's very likely not a conspiracy by a 2-person dev team, but I'll happily remove the Galaxy .dlls if they're bothering people.
Might also be Unity performance reporting service, but there's really no need for that either :)
