I don't use Galaxy, but I was hoping there was a way to manually reset the name.
That's what I thought, just wanted to let you know. I guess it's primarily designed for store clients like Galaxy or Steam.
The developers may not have thought of offline players. :(
I checked the config files but didn't see "Player 1" listed anywhere.
I did that as well, but couldn't find any "Player 1" entries so i think it's hardcoded.
