I thought the Steelbook comes with the book too?
It comes with something similar it appears, but it's listed as a 44 page booklet which many 1st run Arrows often contain. I'm assuming that is some condensed form of the full size 80 page book and in a form that can fit inside the Steelbook. The Weird Science Steelbook and Regular Edition both had the same +/- 40 page booklet
I'm not sure if booklet had less information overall , all the text with less pictures, or if everything is just printed 1/2 size to get it all in.
I've seen some pics of the Regular 3 disc, but none of the full contents of hte SB. The Weird Science Regular edition didn't even have that, just a nice Arrow Style Slipcover and normal Case inside. I think the internal contents were identical, I just like the look of the WS non-SB better plus it matches most of the rest of my Arrow items more closely. I'm certainly not a stickler for uniformity by any definition, but I just liked the regular item better.
