Answer 1

No you can not play a PS3 game on a PS2 it can not read the game disc and can not run the software that makes the game. It's amazing that someone went to the trouble to write the fake answer below

yes you can all you need is a ps2, 4gb usb, ps3 game(any game doesn't matter) and a ps2 controller then go to your ps2 and turn it on then plug in your 4gb usb after insert your ps3 games into the ps2 then wait for the browser to come out after the ps2 memory card display will come out if you look at the bottom you will see a sign that says reading disc wait about a minute then take the ps2 controller push r1 r2 l1 l2 then at the same time push triangle triangle square circle x now your game will come out
