3. Putting Your Gameplay Footage On YouTube
Okay, this one's a bit of a minefield, but in the strictest terms possible - under copyright law - it is illegal. Get comfy while I try and explain it:
"There is an automatic international right that gives the creators of any work (literary, dramatic, musical or artistic) the right to control the ways in which their material may be used, where unauthorised use of said copyright material may lead to legal action or in some cases even criminal charges."
So basically, unless you've written to Activision and asked for permission to show your complete walkthrough of Black Ops 2 (and let's be honest, you haven't), you are breaking the law. It gets even cloudier when you start monetising your clips with adverts - for some reason developers don't like you making money from simply showing off something they created - and a lot have people recently have found their videos disappearing. Of course, there are "fair use" policies, such as showing off gameplay for the purposes of critique or study, and it's generally tolerated by publishers anyway as it's a good form of free advertising for their game. Got it? Yes? Good, because I had to wade through 300 pages of the Federal Copyright Act to write this section.
