Today sees the release of a new feature on the RuneScape website: Development Diaries![help] This new series of articles will take you behind the scenes here at Jagex HQ, so you can all get a better understanding of the work that goes into our regular updates, rather than just seeing the end result.
The first diary[help] takes you through the entire development of the upcoming Impetuous Impulses minigame, but not just a boring step-by-step account: there are some juicy hints about upcoming content, concept artwork to ogle and amusing quotes from our mods, so there should be something in there to interest everyone.
The Development Diaries can be found in the Stories and Letters section of the website, along with Postbag from the Hedge, Players' Gallery and Lores and Histories. We hope you enjoy the diaries!
