Ad Astra Games combines fun with scientific realism. Their award winning Attack Vector: Tactical set of hard science-fiction ship-to-ship 3-D rules is the engine that powers the Saganami Island Tactical Simulator line of products, based on Author David Weber's Honor Harrington books (the "Honorverse"). Ad Astra also produces Power Projection: Fleets, set in Marc Millar's Traveller universe, and based on Jon Tuffley's outstanding Full Thrust game engine.
