Or something more official:
As owner of The Fancy Pants Adventures games, I (Brad Borne) grant any and all players the license to host and monetize footage of my games. Let’s Plays, reviews, commentary, complaining, etc, are all good, as long as the games and assets are used as a whole, and not for unrelated projects (for example, using game music in an unrelated video, characters or animations in another game…).
So go forth and Be Fancy! (then upload it!)
