Code Review

This pull request adds a large list of external web resources and interactive game links to the README.md file. However, modifying README.md directly is not permitted because it is an autogenerated file, and manual edits will cause the CI build to fail. Any documentation updates must be made to the template file instead. Furthermore, the added links are unrelated to the project.

Modifying README.md directly is not allowed because this file is automatically generated during release. As noted in the header of this file, any manual changes will cause the CI build to fail. If documentation updates are needed, they must be made to scripts/templates/readme.ejs instead. Additionally, the added links appear to be unrelated to the Angular CLI project.
