Game Development Matrix (S4, v2 capability-based)

Scenario S4. All asset-creation capabilities covered via the S3/S5 stacks; the structural gap is distribution (Steam/itch/console stores) and alternative engines (Unity/Unreal).

Schema: docs/cli-matrix/matrix_registry.schema.md. Matrix plan: docs/cli-matrix/cli-matrix-plan.md.

Install

cli-hub matrix install game-development
cli-hub matrix info    game-development
cli-hub matrix preflight game-development --json

---

Provider selection constraints

1. Use preflight as an availability report, not as a provider selector.
2. Treat provider order as documentation order only.
3. Choose from user requirements, output quality bar, offline needs, credential state, install cost, and provider notes.
4. Escalate to paid or metered APIs only when credentials are already present or the user explicitly consents.

Preflight

Run cli-hub matrix preflight game-development --json first. Use the manual block below for extra probes or older cli-hub versions.

cli-hub list --json
python - <<'PY'
import importlib.util
for m in ("pygame","arcade","panda3d","ursina","trimesh","pygltflib","PIL",
          "pydub","librosa","music21","mido","abjad","diffusers","replicate",
          "posthog","gymnasium"):
    print(m, importlib.util.find_spec(m) is not None)
PY
for b in godot blender aseprite butler steamcmd ffmpeg pyinstaller; do
  command -v "$b" >/dev/null && echo "$b: yes" || echo "$b: no"
done
for e in STEAM_USERNAME STEAM_PASSWORD ITCH_API_KEY EPIC_DEV_TOKEN \
