Good day! As a consumer with GOG, will I have the same access to achievements here as I would for other platforms? I had heard that Galaxy has an achievement system in place, but just about all of my titles here are much older games that wouldn't have that sort of thing. I was wondering if this is true at all? Or are GOG consumers normally left in the lurch for this sort of thing?

It's a case by case basis and in the case of BG1/2, they don't have achievements on GOG.

The game seems to track achievements in a special section in the saved game. However, the only way I know of to view them is to open the savegame with a viewer/editor. There is no nice webpage or automated upload.

And Steam has respective acheivements. So it's a valid point to ask for them on GOG
