PE Games
A single capable developer can build a useful replacement (AI generator + saved library + big-screen UI) in about a week; the vendor's main durable advantage is teacher authorship/brand, not technical barriers.

No open-source build does this yet
Nothing published replaces this one, so a replacement starts from an empty file. Here is what it would have to cover.
What a replacement has to do
- User supplies year level, equipment, space, time (and optionally curriculum/teaching approach); system calls an LLM to generate a game or full lesson plan, stores the result in a per-user library, allows PDF export and a fullscreen 'big screen' presentation mode.
What it still won’t have
- Native iOS/Android apps and offline saved-library behavior
- Curated teacher-trusted library and editorial quality
- Multi-language support and polished UX of the commercial app
- Subscription management and secure checkout handled by the vendor
What remains hard
- Brand trust

Runnable build prompt
Build a single-developer web app (React frontend, Node/Express backend, Postgres DB) that provides: 1) an AI Game Generator endpoint (integrate OpenAI-style LLM) accepting year level, equipment, space, time, curriculum/teaching approach and returning structured rules/setup/variations; 2) user accounts and a per-user library stored in Postgres; 3) a simple UI to generate, view, save, and list games/lesson plans; 4) PDF export of a saved lesson plan; 5) a fullscreen 'Big Screen' presentation view for classroom display. Out of scope: native iOS/Android apps, offline sync, multi-language translation, and advanced editorial curation. Include error handling for API failures, input validation, unit tests for backend endpoints, and deployment scripts (Docker + basic CI).

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
