Preliminary Study of the Performance of the miniPXI when Measuring Player Experience throughout...
summary
Study tests miniPXI — an 11 single‑item inventory — on two iterations of nine game prototypes with 16 participants and finds the instrument reliably detects changes in nearly all player experience dimensions between versions. The single enjoyment item shows limited sensitivity, so authors propose adding alternatives such as the Net Promoter Score. Results suggest miniPXI is practical for early prototype evaluation and for tracking iteration‑level PX differences during development.
