either a game developer (i have little past experience) or a game reviewer
Being a reviewer is probably harder than being a developer. The pay isn't great, you're more of a target for Internet Trolls and starfishs, people hate you if you dare become friends with any developers (with that said, do make sure you make those relationships public and step away from reviewing their games in case of bias) and a lot of the time your voice is crushed under the many other, louder voices.
As for being a game dev; all you really need to do is just start making stuff, and eventually come up with your own unique, wacky ideas. Do some basic tutorials for free engines to learn the early concepts. Choose a speciality and stick with it; programmers and artists are hired frequently and get better paid jobs and better job security, so they're the fields I recommend.
