I have a few thoughts I'd like to share. For perspective, I was the managing editor / EIC at Siliconera for several years. I helped grow the site from a little blog to one of the primary sources of Japanese videogame news and sales analysis.
Now, I won't get into the more obvious stuff like the money (it's not great) or the benefits (non-existent, unless you care that much about not having to pay for certain games). Instead, let's talk about the Why and Growth aspects of being in the games journalism business.
1. The first question you should ask yourself is why you want to be a game journalist.
Is it because you don't know what you want to do, or is it because you feel it's what you were meant to do with your life? I initially began writing about games as a hobby, but I very quickly realized that educating people about the games industry was something that I felt like I was meant to do. It sounds dramatic, but being a game journalist can often be a thankless job—now more so than ever. Your audience will largely consist of people that have accomplished absolutely nothing in life, yet feel they know better than everyone else, no matter the topic. This is going to be something that you'll deal with a lot, and you have to accept that this is just how the Internet is.
If, despite knowing this, you still feel you want to be a games journalist, ask yourself what you hope to accomplish as one because this is honestly very important. At Siliconera, our goal was to educate our audience and give them some context into the realities of the games business in Japan. Games aren't easy to make.Games aren't easy to sell and make money off of. Marketing (often poo-pooed on forums) comes from an ingenious understanding of the industry and of human psychology. What people consider "laziness" is often a compromise made with full knowledge of the fact that the compromise will be criticized. Design isn't about perfection, but about compromising—it's just a question of what to compromise when.
In essence, the idea was to get people to start respecting developers and publishers. To get them to realize that these are incredibly smart people, and to encourage them to think before making angry statements in the comments section. If we could get even a handful of people to do that everyday, it made me happy. So, again, if you have a similar drive to educate people and are willing to put up with the Internet to do it, be a games journalist. Otherwise, stay away because it won't feel like a very fulfilling job in the long run and you honestly wouldn't be contributing very productively to the industry anyway.
2. The second question you should ask yourself is how you can use the skills you pick up in games journalism to do other things, and if you can turn them into a different career once you inevitably outgrow games journalism.
This is really, really, really important and the answer to this is different for everyone. I haven't been part of the games press for close to three years now, but I made sure I learnt useful things during my time as a games journalist that I could apply to other careers.
I learnt to be analytical, I learnt to be a good communicator, I learnt to organize and study and make sense of data, and most of all I learnt to manage a team of people working toward a common goal. So, while you're podcasting and writing about games and arguing with dumb people on the Internet, make sure to teach yourself practical skills that can be applied outside of games journalism in other careers. You've already mentioned that you're into video editing, and that's fantastic. Don't stop learning new stuff. Learn Excel, learn management, learn a thing or two about business and communication. Learn to understand how people think. Learn how to make the most of limited resources.
Games journalism honestly has a lot to teach people—that's the one thing it's really good for. It's a hell of an education if you take it seriously. You just have to be willing to learn new things by yourself, without somebody else spoonfeeding you.
If you feel like you can navigate all of these tricky waters to pursue a career in games journalism and actually use it to come out a more skilled and better educated person, go for it. But keep in mind, that there's a ton of people that come out completely unemployable at the other end, and that's definitely something you need to watch out for. Don't let yourself settle into that "comfortable" space where you're content writing about games all day for the rest of your life, because it won't last.
