I still get a bit confused but I did some googling and found this,
Making my design document, but I ahve no idea what to put under game mechanics. Do I need to take all the game features I ahve came up with a descibe how they work in detail or what do I write for game mechanics? Someone please help!
Also some others as well.
In a few paragraphs describe the essence of the game. These few words are the seeds from which the design should grow. Planted in the fertile soil of a known market, they should establish roots that anchor the vision firmly in place and help ensure a successful game. This is similar to the description section in the game concept, except that it’s non-narrative and usually expressed clearest in bullet points, though this could vary depending on the type of game.
Trace the typical flow of game play with a detailed description of player activity, paying close attention to the progression of challenge and entertainment. If the core game play is the root of a tree, the game flow is the trunk and the branches. All activity should actualize and extend from the core game play. Be specific about what the player does, though try to use terms like "shoot", "command", "select" and "move" rather than "click", "press" and "drag". This keeps the description distinct from how the actual GUI will work, which is likely to change. Refer readers to specific pages in the User Interface section when you first mention a GUI element such as a screen or window or command bar.
