Vehicle Design System (1.0)
A detailed, generic vehicle-design system for realistically grounded roleplaying games, with support for both conventional and fantastical power plants. It covers vehicle components including power plants, power trains, structures, and other subsystems, using consistent rules to model their performance. Players build vehicles by calculating specifications and balancing individual components rather than selecting from simple preset options. The system is intended for groups that enjoy technical detail and extensive mechanical design.
