Font in scripts:
Fonts in scripts are generally all written in Courier and size 12. This is a standard size font for a script as it is easy enough to read. The font is generally because it leaves all the letters all spaced out the same and makes sure the width of the letter are the same.
Screenplay:
Generally in scripts for screen play, so scripts for anything like; film, TV and radio have character descriptions so that it is easy for the other characters to understand how to act towards a certain character and how to act towards a certain motive/situation. This especially useful for the person playing the role.
Game Scripts:
Game scripts generally use a flow chart. This is mainly because games aren't specific. This means they need to prepare for the game player to make any move, not just one. So the flow chart will include many different things for many different actions so they will know what will happen after each move is made and what the consequences are for each action.
Presenters/characters:
Presenters and characters are generally set out with the name in the centre of one line on the script and their lines below their name in the standard courier font.
Synopsis:
The game will generally include a synopsis as part of the game play because this will tell you what the game is about and give the player a good idea on what moves you want them to make.
Script directions:
Script/Location directions are generally used in scripts for theatre or a play of some sort this could also be used in TV/film. This is useful because it gives the actor more direction on how to act in a certain situation especially a given situation. This also could be important to the script as if it gives locations it could be based on the next scene etc.
