Someone else made an interesting point how a lot of people don't get residuals. That residuals don't make sense for some jobs. For a VA in the background of a small indie games, do you think it's okay for them to require residuals for their work? This lawsuit focuses on large AAA studios but it will set a dangerous precedent. There any many actors who have to find loop holes to build smaller movie projects. "We technically paid ourselves then invested it into the movie" sort of thing.

That said giving everyone residuals is better than giving no one residuals.
