Stryder2931: The patch is less than 150MB, if you download it via the NON Galaxy option. (Download Offline Backup Game Installers).
I do not use Galaxy, so maybe someone can comment if you can download the patch without using Galaxy and apply it that way to save bandwidth.
Edit: Fixed typo.
I didn't use Galaxy initially - downloaded the game, then downloaded and applied patches up to 1.0.2.
Then 1.0.3 came out - via Galaxy first, took hours before it was available as standard download patch. For this reason, I quickly installed Galaxy, ran it, then pointed Galaxy to the Phantom Doctrine game folder. Soon as I did that, it downloaded the 1.0.3 and installed it - it was definitely less than 140 MB, so the installation itself took far longer than the download.
Note that I did NOT grab Galaxy directly from the Phantom Doctrine download area - i.e. I didn't choose the "Galaxy version" of the PD installer. Instead, I went to the generic Galaxy download page to grab Galaxy, then pointed it at PD's folder. It's possible that if you choose to install PD straight away with Galaxy (using the "Galaxy PD installer"), that it will re-download 12 GB all over again. So, don't do that.
If you had already used Galaxy to install it, then it should have picked the patch up automatically. If it didn't for some reason, you should be able to force it to update from within Galaxy. I definitely didn't have to download 12 GB a second time, and I didn't even start off using Galaxy for PD.
Coyro: On my memory GOG patches always came later. Sometimes
a lot later.
The delay with 1.03 was insignificant, so by the end of the day maybe...
ps: the devs are from Poland so by the end of THEIR day. :)
Mawthra: 1.04 is up!
WOOHOO! Though it's Galaxy only so far - IMO it's worth downloading Galaxy just for PD (even if you initially used the offline installers) if you want the patch faster. Just make sure to grab the generic Galaxy and not the one directly from the PD page, because that is potentially the cause of people having to download 12GB for a < 150 MB patch.
