Games have the equivalent of directors who receive millions, like Sid Meier, Tim Sweeny, John Carmack, Gabe Newell, Markus Persson.
And movies have the equivalent of underpaid overworked devs: extras and grips and so on.No, they really don't. Sid Meier, et al, make relatively little of the money of the games sold under their name, with the exception of Carmack and Newell, who own/majority owned their studios outright.
In contrast, the spoils in Hollywood and Music are shared with a much larger group, which sustains the industry in a way that the obscenely hit-based nature of gaming can't.
Also, to note: almost all workers on a Hollywood production (meaning movies released in America, not just those actually made in Hollywood, CA) are union members or protected by union rules even if they aren't yet members. Even extras. After your third role as an extra, you generally have to get/qualify for SAG-AFTRA membership.
Finally: Hollywood has the lovely concept of overtime. I have a great many friends who work in the industry, and they love overtime. It starts at time and a half, and the multiple increases every few hours over the day and week so that theoretically a crew member (but not cast member) could be making 5x of their base hourly rate after a few days of Hollywood's equivalent of crunch time. (Exact amount of hours in a day/week before hourly rates go above 1.5x varies per union, but generally starts at 12 hours/day or 50 hours/week). Needless to say, because abusing their workers gets so expensive, studios plan production to limit crunch time during a production. While it's relatively common for production schedules to include overtime, generally only mismanaged productions run into crunch time.
There is no equivalent in the gaming industry, and so crunch time of a year or two is common (see e.g., EA and Telltale Games). F/X studios operate like gaming studios, so those workers are relatively abused. Like game programmers and other game studio employees, they have largely resisted unionization and so are generally the only group of Hollywood workers that can be said to be both unpaid and overworked.
