Getting into the gaming industry is hard for one reason only. You have a lot of talented competition. I'm not saying this to put you off, but you do need to realise just how tough it is to break into the industry. Currently it's the biggest-grossing industry in the world, so naturally a lot of people want a piece of the pie.
If you want to work for a game development company, you need to show them what you can do. It seems from your description that you prefer to shy away from art and coding which are the two main fields when it comes to making a game. So if it's writing background stories and plots you're after, you should start by writing sample work and sending it to companies that interest you. Even if they don't have openings available, if you're good enough they may consider you for the future or pass on your work to other companies.
Getting into writing reviews and previews is actually quite simple. I do it myself for a gaming website. Ideally you want to start volountarily, doing reviews in your spare time for free. This way people get to see your work and you can build a portfolio of reference work for when you apply for another job. Typically the website should pass on your reviews to the relevent companies that made the game too, so your work will get around.
My advice to you or anyone thinking of doing something similar is sending examples of what you can do to the relevent people. That is the fastest and most efficient way of getting somewhere. You should always be prepared for rejection, but never let that stop you. If you keep trying, companies
will eventually pick up on your determination, you just need a lot of patience.
