Editorial

The second issue of the second volume of IJSG presents papers covering a variety of serious games R&D aspects, from significant user studies to a health application, from an analysis of game-based learning to a description of an interesting system architecture. What I would like to stress is the effort made by several authors – in this one and in previous issues as well – of critically analyzing the values and the features of serious games, in order to pass from the hype of the proclamations – which not always made good to our field - to the rigor and concreteness of science and technology.
