Hero System Rulesbook is the basic rulebook that presents a role-playing system used by all Hero Games products. It uses a simplified game mechanic using primarily six-sided dice to main attributes and skill challenges, a hex grid for maps, and a "point-buy" system for buying skills and powers.
Wow 6 editions of this game. It's my favorite roleplaying system. very versatile and flexible. With 6 editions there are tons of reference and resource books. Recommended to gamers
A good succinct introduction to the excellent Hero System RPG. I read this in order to have a clear idea of the then current rules for several sourcebooks for 4th edition Hero System. This is the 4th edition of the rules published in 1990.
