EPIC is a multiplayer strategy roleplaying game in which you are pitted against or work with real people in various fantasy settings called modules. It starts with Conan and Malazan modules. Third parties can create new modules. The system supports adventures, armies, characters, assassins, guilds/buildings, very rich magic (over 400 spells) and over 2,000 items, in a realistic fantasy world . The game focuses on minimum game time but the maximum amount of time thinking about the game and your cunning plans with your allies. There's no farming or repetition. The game format encourages the creation of epic fantasy tales. Part of a player's turn is in real time, but movement and military orders are done as submitted orders which are processed as your turn.
