I reinstalled windows and noticed that in the risen games my saves were gone....did gog removed the cloud saves ?

Apparently, yes. The game page no longer indicates cloud-saving for all 3 Risen games.

EDIT: My bad... It seems I was wrong.

If true and if not a bug, then that is outright scandalous.

GOG cannot legitimately randomly remove features from games that used to have those features.

That would also be false advertising, since people would have bought the games with the understanding that the Cloud Saves feature listed on the store pages at the time when they bought them would be there permanently, not only for a limited amount time, the latter of which would not be something that GOG would have disclosed to those bought the games when they had Cloud Saves listed as a feature.

That's assuming that those games used to have Cloud Saves. I'm not familiar with those games so I'm going on the assumption that the first two posters' claim that those games used to have Cloud Saves on GOG is correct.

I offer my apologies.

For some stupid reason I was also sure that the Risen games featured Cloud-saves. But after reading your comment I "time-traveled" and saw that at least Risen 3 didn't offer cloud-saves in 2019.

I mus have been mistaking them with the Gothic games features.

Well noticed, Ancient-Red-Dragon

Not all games support cloud saves. The Risen series is one such example.

The problem is that many games were launched before the birth of Galaxy, or at a time when its features were mostly unused, and so cloud saves were never implemented even though in theory they would be compatible with many games that currently don't have them. GOG and developers have not gone back to improve these games because they are now considered old games that probably sell few copies.

There's also been the opposite. Weirdly, games like Assassin's Creed or Far Cry 2 - which never featured cloud-saves on steam - had that feature enabled by GOG some years ago.

Yeah, they probably focused on some popular games that are still selling well. I was hoping that slowly they would be able to implement them on pretty much every game in the catalog, but clearly that's not the case.
