I looked in the Impulse FAQ but there wasn't anything about this in there:
Q. If I purchase a game over Impulse then will I need to download it every time I need to install it or can I just download the setup/install files and install it on my machine?
I'm asking this because I live in a backwater country that has a monopolised broadband industry with absurd download limits at exorbitant prices. I cannot download gigs and gigs a month so a one time download option would best suit me as update patches wouldn't be too much of a bother usually... So do I only download the game data files once and burn to a cd myself or do I have to download them again every time I want to install the game?
