Celetania is a client based MMOG (Massive Multiplayer Online Game) in which ongoing simulations of many galaxies are realized and the players are the master of their own empire. Impressive space battles, which require far-reaching tactical understanding; researching, without old technologies getting redundant; peaceful trading and planetary construction being the fundament of your empire, as well as every player having the potential and chance to write and change history in all of the galaxies are some of the points the game has to offer.
