only two question plz.. answer it

i can install or copy games from blu-ray cd games to ps3 hard disc

there is ps3 games on psn to downloads free it or not

Most games need to be installed before you can play them, which I find odd and annoying. But I don't think you can rip the game onto the HDD and play it without the disc. At least not in any legal way.

Yes, there are a few free PS3 games on PSN, nothing great though.
