Forgotten Futures is an RPG for Victorian and Edwardian scientific romance games, the milieu of Doyle, Verne, Wells and many others.

The mechanics of the game are fairly straight-forward: points buy three stats, broadly-based skills (such as Detective, Mechanic, and Scientist), and optional advantages, with unused points being used for one-off bonuses to rolls. Base mechanic is roll against stat/difficulty. Combat is dangerous, with long recovery times from injury.

The book covers animals, gadgets, historical information on the Victorian-Edwardian era, and extensive notes on running a game in the era (including advice on animals and children characters, and how to run a melodramatic game).
