Ryzom is a "science-fantasy" MMORPG from Winch Gate set on the planet Atys in the year 2531. Originally developed by Nevrax, Ryzom offers Players a living World with rich ecosystems, big MultiPlayer battles, skill-based advancement, role-playing events, PvP, and more. An expansion called the Ryzom Ring was also released, that allows Players to use the game's design tools to create their own role-playing events and scenarios.
Ryzom is one of only a few commercial-grade MMORPGs that are fully open source: client, server, tools, and media. Being open-source means that Ryzom draws on a vibrant community providing fixes and functionality above and beyond that of what the team can provide. It offers Players a unique opportunity to become involved in the development of the game.
There are no Classes in Ryzom, so you’re free to choose whatever path you like, and advance the skills that are important to you. The Game has a ton of different activities, including interactive events with NPCs that offer plenty of possibilities for role-playing interactions. Monsters invade cities, and Players can challenge each other in PvP, but only if all Players consent to it — no anarchic gankbox here!
