Game Design is the process of creating a game, which includes defining its functionality, describing its composing elements, as well as transmiting these informations to the development team. The current work approaches the study of the Game Design present on multi-platform electronic games, analysing how they´re being designed. Being a maturing medium, the academic profile needed for its professionals still isn´t clearly defined, and its language and potencials haven´t been fully explored. The industry´s exorbitant financial return has made it conservative, blinding the creation of meaningful content. With the objective of identifying and justifying the Game Design decisions recurrent on multi-platform electronic games, it is questioned what characteristics affect the way theses games are percepted and played when in different platforms and situations, and which qualities of these situations must be considered during the creative and development processes. The study analyses the Game Design of four titles, comparing their different versions according to their uses on public, private and mobile contexts, through a point-of-view that corresponds to both player and designer.
