There's no doubt that the voice actors are talented and it is certainly true that what they are doing takes a lot of talent and not anyone can do it, but people referencing things like Movie or Animation are horribly out of touch. Many games don't even use voice acting and even in games that use it extensively like The Last of Us, there are still huge sections of time where little to no voice acting occurs. An actor in a movie has a MUCH larger impact on the quality of the movie. A voice actor in an animated show is the same way although to a somewhat lesser extent.
If you really break it down the amount of work the voice actors do in a video game in comparison to everyone else is very small. So, even something like 1% commission when they realistically haven't even done 1% of the work is a lot. I certainly feel as if they are talented enough to be paid more, but the reality is that they are significant enough to be paid more. At least in comparison to Hollywood actors.
