That's interesting, but we (as far as I know) weren't talking about game development, but about TV/movie production.
Most people don't realize it, but many recent high-budget movies were filmed in Georgia, e.g. Fast Five, Vacation, Ant-Man, all three Hunger Games movies, one of the recent X-Men movies, Flight, etc. After 2008, there was an abundance of empty warehouse space here available at deep discounts, not far from the highest volume airport in the world.
As the economy rebounded, momentum in that industry seems to have remained even though there aren't many empty/cheap warehouses here anymore. A few developers are even working on purpose-built movie studios around town now.
It has been interesting to watch, and certainly could parallel what could happen in the bay area if an exodus to somewhere like Austin began in earnest.
