This doesn't really tell us anything. The only answer is that it depends heavily on what the mechanics are like as that's ultimately what defines a game. The setting, theme and art are there for context but they ultimately should serve the gameplay. 

If you have specific mechanics in mind you'd do better to describe those. 
If not then you need to discover a satisfying mechanic worth building a game around before even thinking about anything else.
