Damn the physical copy is a nice package. The glistening, textured cardboard sleeve is really nice. Although it's a little funny that both Blu-rays are in two separate identical cases -- not that I'm complaining about having more of this box art.
Shouldn't be surprised by the quality though, the old PS3 Bioshock had a very similarly attractive cardboard sleeve.
360 version had one too. I wonder if the other bioshock games had one, can't remember.
