"Men Like Gods"
From the back cover:
"The 20th century gave birth to a new genre of fiction:the super-powered adventure. Men and women with strange powers gave a visible expression to the reader's sense of wonder, as they protected ordinary mortals from a variety of threats, from street crime to world-threatening disasters. When roleplaying games were invented, supers quickly became one of their most popular genres – and one of the most challenging to do right."
A completely new work, GURPS Supers draws inspiration from the previous editions.
