An adventure is an exciting or unusual experience. It may also be a bold, usually risky undertaking, with an uncertain outcome. Adventures may be activities with some potential for physical danger such as exploring, skydiving, mountain climbing, river rafting or participating in extreme sports. The term also broadly refers to any enterprise that is potentially fraught with physical, financial or psychological risk, such as a business venture, a love affair, or other major life undertakings .

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!
