What can I say? This is amazing. Absolutely incredible. High production values, very cleanly organized, thought through by a clearly very experienced game designer. If you want to play in a sci-fi setting using the D20 system this is it right here. Stuck for story ideas? Excellent tables and tools throughout. Want to own and upgrade a spaceship and would like a decent spaceship combat that isn't too involved but provides an easy skeleton to dump a bunch of homebrew rules onto if you want? You've got that too. This is one of the better RPG books I've ever seen.
