In RPM package groups, **Amusement** is a top level category and **Game** is its child category. So a game can be categorized as **Amusement/Game/Other**. However, in freedesktop.org specification, **Game** is primary category. **Amusement** is secondary category but not under **Game**. I searched through all KDE apps to find **Amusement** category in desktop files. And find the only one : amor - Amusing Misuse of Resources animation that sits on top of the curent window.
