Game-related services are a different subject btw. Developing games for advertising, doing consulting for game dev companies, etc, is a much more safer bet than making game-based products. However, the game industry doesn't pay as much as other industries, whatever you do in there (at least that was my experience).

Or Sony Online Entertainment.

They have many years and many games under their belts where people pay to beta test their software for them.

It always takes them three goes!
