Why can’t ps4 play ps3 games?

Why can't the PS4 play PS3 games? The PS3 and PS4 use completely different system architectures, which means the PS4 would need to emulate the PS3's system in order to make the games work. The figure often quoted is that a system needs ten times the power of the thing it's emulating in order to do so at full speed.

Can you transfer games from ps3 to ps4?

Select Purchase and your transfer will be complete. If you bought a boxed copy of the game you will need that copy to play it on PS4. This works by after buying the game on the Playstation Store for $9.99, you insert the PS3 disc into your PS4 then start the game up.
