If the content I have was guaranteed to entertain me, several lifetimes. Picked up a few megatorrents of books, even at 1 book a day I'd take decades to blow through it. Knowing my luck I'd get completely bored of most of them in mere weeks/months. Now video games could potentially last me a decent amount of time, got a ton of games fully downloaded, and some of them could be drawn out for hundreds or thousands of hours if played to completion. I've also got a lot of manuals for learning stuff, which could drag things out for a lot longer as I attempt to master something and then utilize it (programming).
