If you have been gaming long and enough and you wish you could still play some of your past favorites in original form like Quest for Glory or King's Quest or Wing Commander... games that have not continued to have sequels or remakes. That's where BC is most important.
Heck even as recent as Gamecube games like Eternal Darkness or Geist or Sega Soccer Slam... if the Wii U could play those, I would have got rid of my Wii by now.
What you will quickly realize is that once the hardware is out of circulation... it becomes a hard thing to do. I will absolutely buy a remade of a PSOne or PS2 game and thankfully a number of those happened for the PS3. What will suck going to PS4 is that all those remakes, and all those PS3 games are now not going to be playable on the PS4 hardware.
What it means to me is that I will be keeping my PS3 save and sound and if I don't have enough space or connections in my entertainment center, then something else will have to be missing... no way I am getting rid of my PS3 anytime soon unless the PS4 hardware had been capable of playing all PS3 content.
