This style is also known as "bracket RP" or "casual RP", among other names(like "stupidity easy Rp"). As the name "casual RP" implies, this type of roleplay is accessible to everyone. The reason for this is that it's easy to grasp and easy to start. However, script-style roleplays will rarely offer much character development or plot advancement; it's usually used as a "pick-up-and-go" roleplay for fooling around. The posts in a script-style roleplay will usually start with the name of the character which will be involved in the post, followed by dialog and action done by that character, and possibly, in-between the name of the character and the dialog, an emotion, most often in parentheses, with which the dialog will be spoken and the actions done.
