To be honest, they're all very easy to "hack", if the user's experienced using computers.
Surely, it's "safer" than nothing, but still, all files can be "ripped" quickly, and it's just not that comportable for the end user with all these protections, I mean, FPSC alone isn't the fastest when it comes to loading time, but then an extraction process before that, too? Takes even longer!
This post isn't to put any of those protections down, just wanted to say, that they're only safe for the average gamers, that don't do much else with their pc's.
