Video game actors are currently on strike, in hopes that withholding their work from video game companies will push them to agree to better actor protections around the use of AI. However, at least one video game CEO - Andrew Wilson of Electronic Arts - doesn't think the strike is going to impact his company for now.
Video games have a very different production flow to film. The same people editing dialog recording are also doing other sound work. The people cleaning mocap also do hand animation. It’s not like film where you hit a brick wall for 90% of your crew if your filming isn’t on schedule.
Things in the short term are done recording and aren’t impacted. Things in the long term can move the resources to other tasks. If a strike goes for six months or a year, they will start seeing issues.
