Whenever I mention to people that I write about video games professionally the immediate response is always "Oh, that must be so great!", followed by "You must receive a lot of free games," not much later. Some of them even think that journalists are at the top of the industry, but the reality is that its the complete opposite.
I personally consider video game journalism to be one of the most difficult forms of journalism to master, and that isn't just because I work in this industry. There is extra responsibility that comes with reporting on video games, and a lot of extra issues that aren't as prevalent in other sectors.
Writing about games professionally means doing justice to the many hours of work developers put into their products. It is about being fair to both consumers and developers and about finding that balance between marketing and press releases and the reception of the final product.
