Those boxes have been around for a while...KOTOR came in one for me, as did GTA III, NWN, BGII, TOB, the three disc version of BG1 ToTSC...
I don't mind the trend too much, as I really did just throw those old boxes away after a little while...heck, I barely even use the cd cases anymore, now that I have my good ole 200 cd case...
