I miss the old big cardboard boxes, which I'd also had on the C64. Going that far back, you'd have Rainbird games such as Jinxter and Guild of Thieves coming packaged with full newspapers, badges and the like - and in the case of The Hitchhiker's Guide to the Galaxy, Joo-Janta 2000 sunglasses (cardboard!), fluff, and No Tea. I think my favourite pc boxed game was Curse of Monkey Island. Just wonderful colours and theme.
I've gotten rid of them all over the years, though, even recently getting rid of all the dvd case boxes I had - on pc at least, I am now completely digital (and 90% digital on Wii U). It's sad that I won't ever get a new game in full cardboard box and to experience that new game smell (you all know the one I'm talking about!), but I just don't have the space for them.
Edit - Now that's what I'm talking about!
