I started writing stories, then made a choose-your-own-adventure style ebook called 'Witches and Bandits and Swords (Oh My)' using MS Word formatting to link the choices to the prose sections and released it on Kindle. After a while, and encouraged by a Big Al's Books and Pals Fantasy Book of the Year nomination I decided to turn it into a game with art and music and stuff XD
After the first coder (a Greek guy I found on Kongregate) pulled out after being too busy, a friend and old workmate, Mike offered to do the coding and we named our 'studio' after the takeaway we used to go on lunch breaks to.
After a couple more visual novel adventures (the Bunny Hill Horror games), we're now starting on a detective point n click with actual gameplay and everything!
How about you, AgentXMan?
