What advice would you give-

[Alex]

What kind of involvement in the industry is he looking for? I don't know his resume at all so don't take this as dismissive or anything. Is he already educated/experienced in the industry?

There are jobs in the LA area, and there are big pockets all over the place (San Francisco, Seattle, Boston, etc). I know several game developers and by coincidence not one of them is in California (Ann Arbor, Orlando, and working from his home in New Hampshire) though all of them work for companies headquartered in California (Blizzard in Irvine, EA and LucasArts both in the San Francisco area).

I certainly would not be one to discourage moving to a place just because it sounds like a good place to live, but the LA and SF areas are both very expensive places to live while twisting in the wind looking for work. My advice would be to move once you have employment rather than move hoping to find it, but everybody has their own tolerance level for the discomfort of risk.
