Video games are becoming much more intricate. #2 Son's favorite video game was Oblivion, which he played for months. Skyrim - the sequel is coming out on Friday (expect him to sit up with a six pack of Monster starting Friday night).
There are serious actors doing the voices - actors like Christopher Plummer.
Not much of a gamer, myself (the original Civilization convinced me that seeing the sun rise through the office window because you were gaming all night is, err, sub-optimal for me). But this industry has become something very interesting indeed.
