This. Besides, what fuels value of gamed to prospective buyers? Are younger, "current gen" folks going to be nostalgic for these games ten or twenty years down the road?
As mentioned before, what about digital downloads? Will it be a matter of just downloading the game or will people hoard their devices if it can't be easily downloaded? I can see it now:"iPhone 4S with Orig. Flappy Bird OMGRare!!!!!!!!!"
I'm going to predict that the market for modern games in the future is going to be pretty small. Many of the games that people (ie regular folk, not "gamers" per se) play are play and toss as they are about a buck a pop or free with ignorable micro transactions. I'd be very surprised if there would be a big push for something like the original "Candy Crush" or something along those lines. People will try to cash in on the concept ("Xbox 360 with Afterburner Climax RARE11112!!!Download") but will more than likely fail at getting anything reasonable or at all for such things.
