Abstract
Almansur is a multiplayer turn based strategy browser game developed throughout the last decade. This project aimed to create a new version of Almansur, focusing on improving the usability of the interface, making it easier to to teach new users, and more efficient to use for the current ones. This document describes the development process of this new version. First the existing game was analyzed, creating a conceptual model, a list of possible tasks in the interface, and comparing it with other games of the same genre. This interface was then tested by player observation and with the Nielsen Heuristics to identify its current usability faults. A new interface was then created, first on paper, then in a simple interactive prototype, and finally in its full implementation, which iterated multiple times through development. Finally the resulting work was tested and compared with the previous version, using both old and new players to the game.
