Stencils

Drawing the fundamental principles of games, so designers can see the structure they are moving through. Published as it happens: sketches, reading notes and open questions.

We are all metanauts.

“Mechanical depth” is two things

One jump, made deeper step by step: first more possible states, then a non-binary state change, then an edge curve driven by several parameters. Drawn as state graphs, the steps do not change the same thing.

The term mechanical depth seems to conflate changes to the size of the graph and changes to the curve of the graph’s edges.

Everything so far, newest first

How this log works

Entries are short and unfinished on purpose. A diagram, a reading note, an open question. New entries appear whenever the research moves, newest first.

The stencils

One shape: the graph

The model has a single foundational shape. Every stencil, from “game” to “playthrough”, is drawn on the same graph.

The stencil for a game: a graph of states inside an ellipse

Game

The foundational stencil: every game as a graph of states and the transitions between them.

Stencil: playing, gaming and cheating as three ways through the same graph

Playing · gaming · cheating

Three ways through the same graph: wandering, taking the efficient route, or skipping the rules altogether.

Explorations

Where the model goes next

Side paths that start from the stencils and wander off. Each one will get its own page.

Exploration

Trauma in a mental graph

Visualising trauma in a mental graph, and collecting ideas for how that could lead to new kinds of gameplay.

Exploration

Playing with shapes

The foundational shapes and spatial elements from the lecture, explored as their own side path.

The metanautical pyramid

Game designers are metanauts: they travel through a space of possible games and move between levels of abstraction while they do it. The pyramid names those levels.

METANAUTIC

A series of videos and streams with Xander and Ziad. Each episode takes one idea from the research and plays it through on real games.
