World of Communities as a concept has started in Ukraine from the idea that citizens should be more engaged in community life because this engagement guarantees sustainable social and economic development of local communities. Since 2016 we have been developing new game tools that allow citizens to take responsibility for their lives and communities, deeply understand how the mechanisms behind healthy and prosperous societies work in practice. World of Communities is developing a national network of practitioners who use serious games and gamification in the field of community development, design and implementation of projects, community development strategies and adult education.
