This project covers the progress of creating an interface for three separate and unique platforms; the computer with keyboard and mouse, the consoles with handheld joypads and the tablet with a direct interaction touch interface. The project uses the Dungeons & Dragons, 5th edition ruleset in order to kick-start the process, and passes through the phases of platform analysis, game-design and lastly the end-result of a prototype design for an interface that attempts to work equally well on all three of the platforms. The problem definition of this project is currently not answered, but it is strongly indicated that it is indeed possible to make these kinds of interfaces without sacrificing user friendliness.
