For me - and I suppose others nowadays - I'm downloading more and more of my games versus actually going and getting the physical copies of them from the store/Amazon. As a consequence, that means I get less and less of all the fun 'physical' manuals, posters, little additional things that you sometimes get inside game cases. For me, I've kept all of my posters from various games (even if they are just game maps) because they are just a great little memory and now that I think about it, I'm starting to miss things like that.
What about you? Are you a convert to the digital age and have no need for such a prehistoric piece of paper or do you miss the feel of the manuals, posters etc. when getting a new game out of the box?
