Hopefully you won't need a digital download. I had a problem with Sims Medieval and that's how EA took care of it. It took 10 hours to download and I have fast internet!!!
Define fast internet. It took me 4 hours to download DarkSpore's 3+ GB and I have a true high speed connection.
At least 4 Mbit. The standard for "high-speed" really does need to be changed if it hasn't already in the US so they can't charge an arm and a leg for anything less than 4 Mbit. I was pushing other heavy traffic things through and was sharing the connection with two other people, and it's a 10 Mbit connection. I'm lucky to get 1 Mbit consistently on anything, though.
