Also - it has to be a fully "installed" copy of the game.
I know that with WoW you can make a backup of the game folder, drop it on any other computer, and play fine. It really helps when moving machines or re-installing an OS as the update process for a fresh install can be... tedious.

I tried the same with Dom3 (copied the game folder and dropped it onto my laptop) and the game would load but I could not do certaion things. My mods were already part of the package so I can't speak to that - but I was not able to complete a turn in the game I was playing. Once I installed the game from the install file everything worked fine.
