Hi, i hope somebody from the devs or from gog reads this.
I am having the same issue i was having with the previous game.
My game saves are getting too big for the cloud storage.
So far i have started deleted many save games and could manage to squeeze the cloud saves in but this will only get worse as my current playthrough progresses.
It is extremely annoying because unlike most people I do actually play on two different machines (main computer at home and laptop when i am on business trips of traveling around)

I would even be willing to pay a small amount for a gog premium feature that gives me unlimited (or whatever large amount) of storage space.

Edit: A wish i have for the devs for any future games would be to have the save files in different folder depening on character. Just like it is displayed in the game. That would make it at least possible to quickly delete unneeded save files without the danger of losing a character.

Some games have more problems with this than others and Pathfinder's save files can become huge. I can believe it comes with the territory as the game has to keep track of a lot of variables in combination with its size.

I have no idea how GOG determines the amount of space allotted per game.

Instead of deleting my save files I put them on a mobile HD should I ever wish to revisit my older playthroughs. It might be a bit more effort but mobile HD these days are small, cheap and you can store plenty on it. You might even use backup software to automatically copy your save games onto the MHD, saving you hassle of doing it manually. Also, it avoids problems when your game has trouble syncing with the cloud rare that may be.
