If you reduce Sector Asgard Kappa down to it's core, the majority of the book is a description of each system and the key (usually habitable) planets within each system. It doesn't sound like much, but it is done in good detail. Each planet/system includes (cool to boring):

• A broadly outlined planetary adventure (Savage Tale)
• A map of the planet
• Sci-fi rich description of the planet's history and where it is now
• Racial stats for the denizens of each planet (players could hail from one of them)
• Several key NPCs (enough to get you started)
• Science Fiction Companion Stats for the planet

You get a well detailed science fiction sandbox.

"A Million Starflies" is the title for the included Plot Point campaign which spans 15 adventures. Naturally, it is setup to make the players travel and explore the sector which in turns allows them to get involved with included planetary Savage Tales or simple random encounters of your own creation.

The bottom line is that you can run this as a sandbox or use the plot point campaign for a bit more focus. Regardless, there are many, many hours of game play here.
