FrEee is an open-source 4X game designed to be an enhanced remake of Malfador Machinations' Space Empires IV.
The name comes, of course, from the fact that the game is open-source, and from the Eee, a race of friendly floating space blobs that will not hesitate to backstab you in SE4!
Is it pronounced "free"? How about "free Eee"? Maybe even "furry"? Who knows...
