Without a doubt, the best way to succeed in the industry is to work. For yourself, or other people, work is still work. The better it is, the more impressive it will be to any and all you share it with.
You don't have to be huge into coding to break in to the gaming industry, but you will need to be a part of a team that creates one or several games before you'll be "established". Try to find start-ups that you can volunteer for, or perhaps try writing for a game/world/universe that exists in your head and then present that to people that code!
If you can "write" an RPG, or story-esque experience that would translate well to a game, then go for it! You may even find that presenting a fully written "game" in an interview can impress. In the end, it's all about hiring people that are capable of making shipped/shippable product. If you can prove you're able to go the distance, you'll find doors cracking open.
Some other suggestions might be to try and write for D&D-style encounters, or possibly for LARPs. It's a large investment in time, but you gain a lot of experience in storyline play-out, as well as how to translate your mysterious/interesting characters into large connective payoffs with real players. You will likely learn basic gaming mechanics as well, which can aid you in writing both for the world AND for the encounters.
