Empirical Analysis of Playability vs. Usability in a Computer Game

This paper reports our experience in applying an empirical userexperience testing method to improve a computer game. We sought to understand the differences in practice between usability and playability, and correspondingly to assess the usefulness of different approaches to taxonomies for playability. Our experience suggests that the evaluation technique for playability can be the same as for usability and that some existing taxonomies for playability do not provide effective support for translating experience of evaluation into heuristics for design. For formative evaluation, understanding episodes for playability depends on specific circumstances of each episode; taxonomies may be more useful for summative evaluation.
