From idea to playable milestone

Use this path when you are starting a new game or rescuing a project that has too many disconnected features.

Build this with XandoRelis
01

Define the fantasy

Write what the player should feel, not just what features the game will contain.

02

Prototype the core action

Build the smallest playable version of movement, conflict, reward, and failure.

03

Measure the build

Check feel, pacing, frame rate, bugs, readability, and whether players understand the goal.

04

Plan the vertical slice

Lock a representative mission, level, match, or session that proves the full game direction.

Before you write the first task

Target platform and device rangePC, mobile, web, or console-ready decisions affect every technical choice.
Reference games with reasonsName what you like: camera, combat feel, economy, mood, pacing, or UI clarity.
First playable milestoneChoose the smallest build that can prove whether the game is fun.
Risk listIdentify networking, content volume, controls, performance, art style, or monetization risks early.
