Cheers man, I actually have very little experience with videogame design and development bar some middleware experience and some light programming, I haven't a portfolio or anything, I stopped for a while whilst I studied film and media at a college level because I began to hate videogames, mainstream games usually bore the hell out of me and I needed something new. I play a lot of indie games, mostly indie games in fact, and do little reviews and write ups every now and again, If it wasn't for the indie scene I would never have thought about getting into game design.
I think everyone has picked up a map editor at some point, I used to have a ton of awful CS Source maps I made knocking about. I'm in the process of teaching myself Unity and a few languages, hopefully I'll have something to show for my effort at some point, but I am or was notoriously unproductive. The last 'game' I actually completed to a point was a 6 month collaborative project in RPG Maker with a friend, that was a very long time ago.
