So I decided to download from Origin (yes... I know) and only for DA:OU it's a 27 Gb file. Apparently, if you download from Amazon it's a 12.4 Gb download, at least according to the product description... what's the deal with that?
I received the following response from Amazon (less than two hours after asking!):
"The file size listed on the product page is for the size of the file that downloads from us. This is the file that EA gave us to provide to customers who purchase the software via our website. However, this file does not include any updates that EA has done since it was initially released. The file that downloads directly from the Origin client will have the base file, same as what you would download from us, and any updates that have been released."
It seems odd to me that there are 14.6 Gb of "updates" to the Ultimate edition of the game. Perhaps it's the DLC, but still... Anybody has any comments?
