The videogame industry has suffered significant modifications in the last years, broadening its horizons towards a more casual market. This market expansion not only brings new opportunities from an interaction point-of-view, but also new challenges with the inclusion of users who are not accustomed to these games.

The experiment addressed here assesses different gameplay mechanics influence not only a subset of the players' physiological signals, but also their performance and interactive behavior.
