I am working on building a HTML5 RTS game, and my current state is that I am building the Campaign mode of the game, and want to define the gameplay (The Scoring, Unit Behaviors/Attributes).

I am searching for links/articles/books about how to define the gameplay, for me this:

• The scoring
• Figuring out levels of control (in any RTS game, there is units, individuals and squads)
• Unit action/attributes/properties
• point timing (how long it will take to play?)
• Achievements
• ..etc

I want to see how they usually define these areas in RTS games, I expect to see general document discussing this concept that I can use to build the gameplay.

Any idea? Is my question clear or I need to provide more details?
