It's a bit hard to say. For the most part, I do want to play 90+% of the games I own (pretty much everything but the sim sports games), but my overall lack of freetime means that the backlog grows quicker than I can whittle it down. Right now, out of all the physical games I own, I can only say I've finished a little under a fifth of them, and that's just the physical backlog. I think I'd need a few weeks in the Hyperbolic Time Chamber to get anywhere.
