Yeah, this is definitely tricky. On the one hand, companies do have the right to protect their IP... but on the other hand, I think that gameplay footage is different enough from something like showing a movie that companies probably shouldn't have the right to do this kind of thing. Gameplay is always going to be different, and people should be able to monetize gameplay footage videos.

Music in games can be a trickier issue, since that's not really transformative as gameplay is, but ideally it should be considered to be just a part of the game just like the graphics are.
