I meant timeless in the sense of the physical medium. Though video games probably decline in interest faster than books it is still the same concept, and not something that should be able to bar their inclusion.

If I want to read Patriot Games I go down to the library, check it out and read it. Same as I would in 1987. If I wanted to play FFI it would require me to still have an NES kicking around, which very few people do.

I didn't think of this before, but it is way easier to emulate an old game than to find a copy of an old book to download. This isn't something libraries should really be able to base policy on, but I imagine it seriously cuts in to demand.
