Deus Ex: Human Revolution Install Size Revealed
Free up your harddrives, because Deus Ex: Human Revolution is coming to eat it up. If you’re picking up the game on PS3, you’re going to need to clear up 3GB of harddrive space for the initial installation. That 3GB install is mandatory to play the game.
If you’re grabbing the newest of the Deus Ex series on the Xbox 360, you won’t need to install anything but will want to keep 66MB free to play the game.

That’s it? I was expecting it to be a little more than that. I’m just not looking forward to the install time when I start playing the game.
