I don't know, as I've not attempted to enter other fields. I would think it would be easier than, say, film effects work, though, predominanty because the vast majority of film effects studios (at least, in the USA) are located in California, which makes sense, seeing as Hollywood is there. Game studios, though, are spread out across the country a little more (although there are 'hubs' in California, Washington, and Texas where there are a good number close to proximity to each other).
