Quill: A Letter-Writing Role-Playing Game is a gem that really surprised me. It's fun, but more importantly, it is an amazing tool for academic writing purposes, perfect for weaker writers and students with dyslexia. By itself, it's not perfect, but it's a genuine trove of ideas that mean well and work well. Plus, it's PWYW. Easily 5 stars from me.
