This document discusses user experience (UX) design considerations for video games. While many standard UX methods like user testing and heuristics apply to games, there are some differences in what is tested (e.g. fun and engagement rather than just usability) and metrics measured (e.g. interest in storyline rather than efficiency). Game UX also focuses more on gameplay challenges than reducing steps. Examples demonstrate how games teach players through level design, feedback, and calls to action rather than just conveying information.
