Book excerpt: The ISAGA 50th Anniversary Conference proceedings is a collection of 76 accepted submissions. The proposed papers and posters are very diversified and have backgrounds in many areas, yet they come together in the simulation and gaming. We had 12 tracks for papers, a poster submission track, workshops track, and thematic sessions proposals track. The 50th anniversary track will allow us to look back at our heritage. The core tracks with the biggest number of submissions are the simulation and gaming track and game science theory track. For the first time, we also had tracks for gaming technology, AR/VR, e-sport science and gaming cultures, we have received many interesting and quality submissions, which will add new perspective and diversity to our field. ISAGA wants to stay relevant and up-to-date with the current problems; thus the tracks for S&G for logistics and smart infrastructure, gaming for individual efficacy and performance and gaming for sustainable development goals. We have also received ten poster submissions with very interesting topics.
