Game Design

The practice of defining a game's rules, mechanics, systems, challenges, story and player experience so that it is engaging and playable. It is separate from programming and art, though the three work closely together.

A framework that describes games through mechanics (rules and data), dynamics (behaviour at runtime) and aesthetics (the emotional responses of players). See the MDA paper by Hunicke, LeBlanc and Zubek.

Read the MDA paper and Game Developer design articles, watch design analyses such as Game Maker's Toolkit, build small prototypes, join a game jam such as Ludum Dare and collect feedback from players.

A document that describes a game's concept, mechanics, systems, content and goals so a team shares one vision. It can be short and iterated, and many teams use light formats rather than long specifications.

Twine, ink and Yarn Spinner for branching dialogue and stories, and articy:draft for planning larger narrative projects. Ren'Py suits visual novels.

Watch real players try it without coaching, record where they struggle and what they enjoy, and iterate. Services such as PlaytestCloud and analytics tools such as GameAnalytics help once you have a build.

Offer remappable controls, subtitles, colour-blind options, difficulty and pacing choices and clear feedback. See the Game Accessibility Guidelines and the Xbox Accessibility Guidelines.
