A hex-based, miniatures ruleset for aerial combat in World War II.
The game emphasizes the importance of speed, altitude and pilot skill in the chaos of air combat. It includes statistics for many frontline fighters, and a pilot advancement system for campaign games.
All games in the Fly Fight Win series are designed for playability, but retain sufficient detail to recreate plausibly historical outcomes. Most scenarios can be played in around 90 minutes.
There are enough changes from the Warbirds game to warrant a new title.
