Requiem for Innocence: Precursors ('RFI: Precursors', or just 'Precursors' for short) is an open source MMO-styled game, set in a science fiction epic. The universe is vast and multi-layered, with several factions all in conflict with each other... everything you would expect from a classic science fiction epic. The game itself is designed to be fun and enjoyable, and suitable for casual players and small groups.
