Computer Engineer and M. Sc. in Computer Science from Rio de Janeiro, Brazil. His first contact with videogames was with Super Mario Bros for NES and with the Atari VCS, and then a question sparkled in his brain: How games are made? That question led him to a new dimension, moving from his countryside city to the capital and meeting people with the same interest. Then he could finally answer his question, but it brought many others: Why people play? Why are games fun? How can we improve them? How society and games affect each other? His quest continues!
