You must have missed all the non car analogies. And part of the point is that the way video games are protected is more like movies when they should be more like board games. Part of the point is that the way they are protected is not consistent with what they are. They are not movies or fixed experiences, they are games designed to be played. Each play is unique. Protecting them the same way movies are doesn't make sense.
I didn't miss the non-car analogies, but I saw one and sought to correct it. If anyone read that post and found themsolves nodding along saying "Yeah, if I film my car I don't have to pay. Why should I for videogames?" then they're misunderstanding the respective regimes under which the intellectual property is protected.
I absolutely agree with the bolded. Particularly, the way that source code for computer programs is protected as a
"literary work" seems, to me, completely asinine (but that doesn't really bear on what we're talking about here). However, videogames do (almost always) contain artistic, musical and artistic works. And just by buying the game you don't have the right to do
any of these things with those works without a license.
I think the law will catch up in time, but it's often slow. Ultimately, I think we may end up seeing videos like Let's Plays being shoehorned into the existing copyright regime somewhere, maybe as collaborative works or possibly as computer-generated works.
