Something caught my eyes from the PTOM review of the game (see this thread)

Here is a quote from Page 40 (first column, the beginning of the second paragraph):

Surprises begin right from the moment the game starts (after the install process, which also happens before the starts of a new act).

 

 So the installation process is not a one-off thing? :(

 

 thats not a bad thing, it means that it replaces the old file with a new one taking up less space.
