I've written a lot of gaming articles about different things over the years; my first one was accepted for publication in 'Arcane' magazine (who sadly closed their doors before it got published), some appeared in my old e-zine 'ODDS', I tried to self-publish a book about them and I featured them on my blog.
Right now they're appearing in a serialised column on RPG.net and they cover detailed thoughts to simple observations; in fact, once I realised that my articles were just me talking about what I've experienced in the hobby, and conclusions I've come to because of those observations, that's what I named the column; 'Observations From A Gamer's Chair'. They stopped being about hints and tips and became more about me sharing my experiences.
There are 48 articles available to view at the monent with another ten to come. It'll be a shame when the column is finished, but I've had a great time writing them and venting/sharing/exorcising my thoughts and feelings on all kinds of gaming subjects. I have no intention of writing any more as I focus more on game design and creating adventures rather than writing about playing them.
Maybe there's a game design column in there, somewhere. I need more experience first.
