Digital Download taking over 18 hours to download

Sorry to hear it. If you are using other devices then you would see a decrease in your download speed. Especially if you're using wireless. If you are using wireless then I'd recommend using an ethernet connection for the duration of the download.

i got the download but its taking so long to download im at 71% n i took 18 hours now

If you have a friend with a game on disc, you can install it on your console, then if you buy the digital version it will just unlock the game you've already installed rather than you having to download it.

I checked a couple of download time calculator sites and 17-18 hours is how long it takes to download 38 GB with a 5 Mbps connection, so 15 hours is actually better than you would expect with a connection of that speed.

Are you downloading from a disc or a digital download? It took about 5 hours to download call of duty as a digital game. If downloading the digital version it will take quite a while depending on your internet speed. If downloading from a disc try disconnecting
from the internet and downloading the game that way.

Lets all pay £54.99 for the digital version which takes a week to download....or buy a disc copy for £39 and install it within an hour! Although mine did refuse to budge from queued>installing for over half an hour because I tried downloading the update
at the same time, after a little alteration I was fine. I do prefer the convenience of digital though.
