Downloading or otherwise obtaining an in-use license of any game, unless you own it, is illegal. Not to mention dangerous, what with all the viruses out there. The companies have to make their money somehow.
Fortunately, you can get PS3 games for free, legally. It'll take time and effort, and it certainly won't be instantaneous.
For signing up, you get 250 points, which is $2.50. After that, you can complete offers and surveys, play games, win contests, and refer others to the site for more points. The site is linked with Amazon.com, so then you can spend your points there to get whatever you like for FREE. It isn't a scam--you can ask anybody. In just ten days I have $36. If you put some effort in, you could easily get your first game for free in a week or two.
If you have any questions about the site, feel free to ask me. I've also written up some further information on how to complete offers, how the site works
