The ICRC is actually only pushing this for "real-war" simulations. I don't think Madworld is very realistic, as much as I'd love my own chainsaw gauntlet.
Though I don't agree with the whole lobbying congress to make it law thing, I think it could work for some games. As long as the developers are ok with it, adding war crime laws to video games could be educational and add to the realism.
I think "impulsive" narcissism can be ruled out. I'm not saying narcissism has absolutely zero to do with it. But Snowden joined the NSA because he was planning to find and release info on NSA's abuses if they existed, so it was anything but the impulsive nature of any ordinary disgruntled NSA employee.
It's kinda funny since most people, at least from my experience, don't have a problem freely pirating games older than ~15 years even those that don't pirate games normally. And that's if the developers haven't already released their old content for free or next to nothing anyway.
My favorite is page 8, where you will notice they have graciously left the position of the 11th and 13th on the page un-redacted. As you will notice the contents of the footnotes 11, 12, and 13 are redacted, but the existence of a 12th foot note is indisputable.
So, the question remains, why redact the position of the 12th foot note whilst the others remain free for terrorist to see? It can only mean that the position of the 12th footnote on page 8 is of grave and strategical importance for our national security! Handing over the position of foot note 12 to the public would cause irreparable damage to the nation. If we gave away its secrets the terrorist win. Bombs and Taliban everywhere. Thanks Obama.
