<You can buy an old book and read it the same way that a reader could when it was released.
Wrong. Try reading KJV some time, it was written for a different audience with a different language (Old and Middle English might still be English, but they are not 100% the same as modern English).
>You can buy an old movie and watch it the same way that a viewer could when it was released.
What? Laserdiscs, anyone? (and outside movies: 8 track? 8" or 5¼ floppy discs?) Standards move on, and old standards are not always grandfathered in.
>There are libraries made to collect and catalog every book written, but what do you do when you want to play a game only ever released on the PS1?
Buy everything needed for a classic setup, or emulate. Official emulations or unofficial.
>With the Xbox 360's laughably bad hardware problems will it even be possible to play Fable 2 in twenty years?
On OG hardware? Doubtful. I don't think the 360 will see the long term nostalgia love like, say, the NES did (does).
>Why are pirates who have been vilified by mainstream media the sole guardians of old games?
They aren't, have you not heard of something like Nintendo's virtual console?
>Can every video game be saved for future generations?
Considering how easy storage has kept up with game growth, yeah. 80s games were KB-MB in size, 90s games were MB-GB in size, 2000+ has just been a matter of GB. I don't think games will get as large as 1+ terabytes any time soon, although they'll get there eventually (given that storage mediums don't make some radical change soon, like 3D crystals or some ayy lmao shit).
>Should every video game be saved for future generations?
The alternative would be allowing someone else to write history.
>Should the golden, game of the year, platinum, definitive collector's edition be the only one saved?
No, as storage is cheap there is no reason not to keep a digital copy of everything. In regards to "should" or "should not" then collectors will dictate the market as to what is really worth saving for those in-group who actually care.
>Even on pc, we might eventually have to switch operating systems when we want to play a different game.
…how fucking old are you? Did you not upgrade from 3.1 to 95? 95 to 98? 98 to XP? XP to 7?
