Project Darkstar was designed as a massively multiplayer online game server platform to enable games to scale to large numbers of players. It was rebuilt from the ground up to be stable, scalable, and not tied to a single platform. In contrast to typical game servers which struggle after 10,000 players and require extensive custom work, Project Darkstar aimed to help games support massive numbers of players in a pluggable and simplified way. This open source project intended to level the playing field for smaller game developers and stimulate new ideas and experiences in the online games industry.
