About MAG

At MAG we have a firm belief that the key to producing great games is teamwork and trust. We are about 90 friendly people working in our offices in Stockholm and Brighton. Each team owns its respective game project and decides on how best to proceed in development. This way, everyone at MAG feels valued and has the opportunity to make a great impact and get a lot of ownership within a positive environment.

In order to drive innovation and learning within the company, we have monthly hackathons during which everyone in the company comes together to learn new things, work on side projects, develop game concepts, and/or build prototypes for new games. We believe that happy people with the freedom to flex their creativity make great entertainment, and this is how we nicknamed ourselves The Good Times Factory. Making great games should be fun, and we encourage that!
