Great Googly Moogly! The print on demand version of kosmic just dropped, these are the complete core rules for the Solis People of the Sun setting (a unique setting detailing 521 of the nearest star systems to Earth with accurate 3D to 2D maps). 354 pages of goodness, 100+ color images, Kosmic is derived from Cepheus Engine, and is hardish-space opera, it has 39 different careers with 117 branches, or fields; slightly different tech tree pushing grav to higher TL so that other vehicles are still relevant, hex movement for spacecraft, plus much more.
