The reason we don't have #BigBoxPackaging for #Games anymore is due to #GameConsoles:
With the rise of the #PS2 & #Xbox360, the "#DVD #JewelCase" became the norm and #EconomiesOfScale kicked in.
Also #OnlineStores kicked off and #Retail demanded more efficient #ShelfSpace and was unwilling to accept bigger boxes than for DVDs.
It's the same reason #BluRay, #HDDVD & #HDVMD (LOL!) have almost identical packaging and why we get super cursed packaging like a 24-disc case that is barely triple-wide...
