Game Play Driven

Gameplay Driven

On the other hand there is the gameplay driven design which will be probably a light engaging game.  This means that the game will motivate the player to play the game for the fun itself.  If the player ever gets tired (which will probably happen) then the game will be over. 

The design of a gameplay driven game is somehow faster than a story driven game: the designer must only think about the main game mechanic (the initial idea) and develop it in order to adjust it to some difficulty management along the game experience.  Some designers prefer not leaving everything to just some difficulty tweaks and create a simple story ocurring along with the evolution of the main game mechanics.

Assuming the gameplay idea is very good (and is more probable for this to happen than in a story driven game) then there is a great advantage that can be taken into account for games developed with a game mechanic in mind from the start: it is easier to create a story that matches a game mechanic than creating a game mechanic which matches a story.  It is also easier to adding the fun factor to a game when the gameplay is being thought from the start.
