It's a joke, but it's true that CBS claimed copyright on that video. You can see him rant about it on facebook. Since I have no clue how CBS work, here's a link to his facebook. The rant was posted yesterday. It's actually a rant about companies using sneaky tactics to take over other people's content and youtube not notifying the owner and not checking their facts. The video is 100% Fire Emblem. All of it came from the game.
