Diablo III: Reaper of Souls - Ultimate Evil Edition for the PlayStation 4 is a 58.4GB download in Europe and a 26.1GB download in the U.S., according to their respective listings on the PlayStation Store.

When Installed on PC, Diablo III and the Reaper of Souls expansion pack take up a little less than 15GB. The 58.4GB download sounds especially large given the fact that the PlayStation 4 comes with a 500GB, though users can replace it with bigger hard drives.

To illustrate just how hefty of a download the European version is, consider that Titanfall was about a 20GB download on PC, and 48GB when installed, due mostly to its uncompressed audio.

The difference between the U.S. and European versions of the game could be due to multiple language audio tracks in the European version, as well as multiple language cutscenes.

Some European commenters on the PlayStation Blog are reporting that preordering the game is queueing up multiple downloads. One is 20.5GB and seems to be just the English version of the game, and another is 37.8GB and seems to contain the European localization, though it's unclear if users can choose which to download.

We've reached out to Activision for comment and will update this story as we receive new information.

Diablo III: Ultimate Evil Edition launches August 19 for Xbox 360, Xbox One, PS3, and PS4. The game contains the main Diablo III game and the Reaper of Souls expansion. As we learned at E3, the PS4 version of the game includes infected from The Last of Us, as well as a special Shadow of the Colossus transmog set.
