VideoGameAttorney here to answer questions about fair use, copyright, or whatever the heck else you want to know!
I've had two great AMAs in this sub over the past two years, and a 100 more in /r/gamedev. I've been summoned all over Reddit lately for fair use questions, so I came here to answer anything you want to know.
I also wrote the quick article I recommend you read: http://ryanmorrisonlaw.com/a-laymans-guide-to-copyright-fair-use-and-the-dmca-takedown-system/
DISCLAIMER: Nothing in this post creates an attorney/client relationship. The only advice I can and will give in this post is GENERAL legal guidance. Your specific facts will almost always change the outcome, and you should always seek an attorney before moving forward. I'm an American attorney licensed in New York. And even though none of this is about retaining clients, it's much safer for me to throw in: THIS IS ATTORNEY ADVERTISING. Prior results do not guarantee similar future outcomes.
As the last two times. I will answer ALL questions asked in the first 24 hours
Edit: Okay, I tried, but you beat me. Over 5k messages (which includes comments) within the inbox, and I can't get to them all. I'll keep answering over the next week all I can, but if I miss you, please feel free to reach back out after things calm down. Thanks for making this a fun experience as always!
