Are you sure you have a computer with no internet connection?
What kind of question is that? I could move it one time to a place to connect it, yes. But I wouldn’t do it each time to play a simple game like Trainfever. If it is a one time registration, ok. If it is something stupid like the everytime login for offline games like Skyrim, I will have to rethink my plans of ordering two copies.
And I won’t have to download the game, since I ordered boxed versions. Patches can be copied to sticks, you don’t need internet on every computer 😉
