But with a Steam install, you should not need to reinstall that base 1.6 GB part of the game, right, since it resides in a freely accessible folder that you can copy/paste. You should be able to copy everything over to the new PC and point the local program to the new location of the 110+ GB core content. All without going online right? (of course you need to go online when you start it up, but all the setup legwork of transferring to a new PC should be possible with no network connection at all, if my understanding is correct)
