Adventure!

Adventure! is a pulp action role-playing game originally printed by White Wolf Game Studio, the third and last book in the Trinity Universe line of games. The game, printed in black and white on pulp-like sepia paper to resemble a period piece, was conceived as a one-book game line, and was never supported by official supplements. Despite having a vocal fanbase, the Trinity Universe line was discontinued shortly after the game's publication; a d20 system version was released in 2004. In 2002, "Adventure!" won the Origins Award for "Best Role-Playing Game of 2001". Onyx Path Publishing has recently acquired the rights to the Trinity Universe and has announced its intention to release a new edition of "Adventure!"

The Aeon Society for Gentlemen, founded by philanthropist Maxwell Mercer, is trying to bring together as many "Inspired" characters as possible, supporting and coordinating them in their effort for the betterment of all of humanity. But darkness lurks, and Mercer's champions will have to face it in the most unlikely locales. There are three archetypes ("character classes") for players to choose from:
Game system.
Set to emulate the exploits of Saturday matinee serials and pulp magazine action, "Adventure!" uses a very loose and flexible variant of the White Wolf proprietary Storyteller System. "Adventure!" adds significantly to the Storyteller System in three areas: Knacks, Inspiration and Super-Science.
Knacks.
Knacks are powers that differentiate adventurers and villains from normal human beings.
Inspiration.
Inspiration is used to activate knacks, alter the story significantly (either as an instantaneous feat or by altering a potential cliffhanger to better suit the player) increase the number of dice you roll for an action or gain intuitive knowledge to move the story along. There are three facets, and associated traits, to Inspiration, each with their own advantages:
