On game piracy, I think the amount of pirated stuff also comes from how the developer decides to distribute his work and his public image (which is like a thing now that social networking is tops). Aside from the amount of anti-piracy features it carries (which do the opposite in deterring piracy ironically as mentioned with SPORE), it also about realizing the developer's progress and stake in his work. Projects spawned from Kickstarter for example, get more people to realize what exactly it takes for the game itself to develop and how much will get it to work even more. Kickstarter supporters become more sympathetic and turn to avid supporters when the project finally kicks off.

Secondly, developers have to realize that nothing lasts forever and unless the game has a unique feature or circumstance that makes pirating it really bad, they have to learn to unleash their work into the world someday. It's all about, knowing how much you can make off of something before making it available to everyone. And they have to do it quickly too instead of letting the market saturate and turn to piracy for the answer. Yahtzee for example profitted from his Chzo Mythos Quadrilogy for years before finally making it a free series to download. And certain indie games are being re-released in the form of bundles, which are kind of a thing right now.

And then you have the developers who release games for free for the sake of a portfolio or "for the art" as it were like the guy who made Iji or the Ben Jordan series. But that's another story.
