I am posting this in reference to Final Fantasy VIII Remaster. Because they updated it. But this could be used with any of the steam games. Just would have different IDs.
https://www.youtube.com/watch?v=SO8wdhK-VUg <--- reference video shows how to do this with Skyrim.
Run this with Windows Key + R:
steam://nav/console
In Steam console run:
download_depot 1026680 1026681 6690602264714227718
It will download the release build of Final Fantasy VIII Remaster.
When the download is complete it'll tell you in the console where it was saved
Downloading depot 1026681 (2211 MB) ...
ExecuteSteamURL: "steam://open/downloads"
ExecuteSteamURL: "steam://open/downloads"
Depot download complete : "C:\Program Files (x86)\Steam\steamapps\content\app_1026680\depot_1026681" (28 files, manifest 6690602264714227718)
You will have to manually grab the files and move them into the correct folder.
What that command is:
download_depot [APP_ID] [DEPOT_ID] [MANAFEST_ID]
To get ids:
https://steamdb.info/app/1026680/ <--- FF8 Remaster on that site goto depots.
https://steamdb.info/app/1026680/depots/ <--- Click the depot id for the one that actually contains the game files.
https://steamdb.info/depot/1026681/ <--- Click on the Manifests and look for the id for the build you want using the date as a reference.
