I greet everyone, I am a sailor and while I am at sea I have practically no access to the Internet, but I would like to continue to receive achievements in games. I know that there are games that give achievements even in offline mode, and download them when access to the network appears, help expand their list. Thanks to everyone who responds. Now I know for sure about three games
1) Kingdome come
2)Grim dawn
3) divinity original sin 2
4) Darksiders III
5)My Friend Pedro
6) battletech
Sorry fo Google translate)

- Darksiders III
- My Friend Pedro

I finished these games before i started using Galaxy. The achievements popped up immediately the first time i launched the games with Galaxy.

- BLACKHOLE
- Reventure

These two games should also have this feature. Surely there are many others, but unfortunately not many make intentional tests because the risk is to lose the achievements.

I don't use Galaxy, but this thread might help you out.

In general, any of the newer Spiderweb Games, Avernum remakes, Avadon, and Queen's Wish. The GOG versions do not have public achievements, but private achievements specific to that installation of the game are available.

Original War?

Secret Files 3 has them.
