From the back of the book:
Limitless Mecha Possibilities!
Big Robots, Cool Starships is the multi-genre mecha design and combat supplement for Big Eyes, Small Mouth and the Tri-Stat System(tm).
The book contains the necessary mechanics to run a mecha-heavy campaign featuring the exploits of angst-ridden pilots, sleek combat cyborgs, bold starship captain, and a limitless number of other anime mecha archetypes. But it doesn't stop there! BRCS is sufficiently flexible to allow players and GMs to design and stat-out nearly any robot, vehicle, structure, or giant monster from any genre in a matter of minutes - from motor bikes to space stations, mecha dragons to pirate ships. All this from a flexible creation system that minimizes overly-complex game mechanics and maximizes your creative potential!
