The Realtime Art Manifesto was written in 2006, but I’ve only just read it now, and I figure that many others may have been unaware of it too.
This manifesto is about what kind of games we should be designing and building. It is very thoughtful, and written in a poetic style. Many of the statements can easily apply to areas outside of games.
There have been several game-related manifestoes over the past few years: some focus on independent development, like the Scratchware Manifesto and the Manifesto Manifesto; some are area-specific screeds, like the Turku Manifesto; there are manifestoes I don’t really feel like linking, because they are misguided and damaging, like Dogma 2001; and there are manifestoes about manifestoes, such as The Videogame Revolution I Want. But the Realtime Art Manifesto is by far my favorite. It has its heart in the right place, and it’s a deeper place than where the rest of the manifestoes reside.
The Realtime Art Manifesto is not perfect — it is at times too specific about certain kinds of games; this specificity makes the document less universal, and also too long. But I wish that more designers thought this way. All designers should read it. Here is the link again, so that you can read it.
