It is your lucky day Renegade, so it will take a mere 48 hours for you! Just two days, non-stop, while battling Murphy. For this endeavour, you will be rewarded with a game only Lasting for a quarter of the amount of time you put in the download. Isn't that nice?

I guess the download requires you to use the game rather than a download managed as well, so no resuming or things of the like. But even if you can resume, 500 mo to download is quite ludicrous; it would be hardly acceptable even for a MMORPG.
