Grim Dawn Without Steam?

Is there any way to run the Steam version of Grim Dawn without Steam?
My thought is that I could put the game files on a thumb drive and add a couple steam dlls or registry keys.

I know this wouldn’t be recommended, but I would think it to be possible.
I’m sure it wouldn’t get updates and stuff (that would be my responsibility).

If you want to play Grim Dawn without steam or a internet connection your only legal way to do so is GOG.

What bothers you about Steam offline mode ?

Going off of this part, he wants to take the game on an external device and play it on other Computers, that I assume do not have Steam pre-installed.

What I found is to turn off your Steam account from loading online. Should be in the file settings at the top left of the account screen. You won’t get any updates until you turn it back on, but, thats the way I play:p
