Retrobarcelona, the classic and vintage videogame fair, is celebrating its fourth year at the Fira de Barcelona as part of the Barcelona GamesWorld event, from October 6 to 9. You'll find conferences, exhibition, a market, and a big space for gaming where there will be tournaments as well. There will also be a space dedicated to e-sports, robotics and manga, among other things to see and do. And once again this year there will be a charitable side, videogames for food, which last year saw 6 tonnes of non-perishable products collected to donate to the Banco de Alimentos food bank. The advance ticket price for Barcelona GamesWorld is €12/day, and that give you access to Retrobarcelona.
