I'm trying to get Stardew Valley for my mom. I wanted to buy it on here, and then just download + install the file to her computer via flash drive. She has no internet at her home so i'm just double checking before I attempt this. My assumption was i'd have to download an updated GoG client and stardew valley, move them to flash drive, then run them on her computer?

Great! thank you for the information!

There will be an update any day (most probably) beginning of next week since one was pushed to Galaxy too late for GOG to make an offline installer.

That's the point of DRM-free. Works for every game here for single player except Gwent (which is a pure multiplayer game at heart).

If you need more gaming recommendations for your mom, just post here on the forums. Most people here are really helpful, and some of the members are quite senior themselves.
