Rick Priestley in the context of "Warhammer (game)"

Warhammer (formerly Warhammer Fantasy Battle or just Warhammer Fantasy) is a British tabletop miniature wargame with a medieval fantasy theme. The game was created by Bryan Ansell, Richard Halliwell, and Rick Priestley, and first published by the Games Workshop company in 1983.

As in other miniature wargames, players use miniature models (minis) to represent warriors. The playing field is a model battlefield comprising models of buildings, trees, hills, and other terrain features. Players take turns moving their model warriors across the playing field and simulate a battle. The outcomes of fights between the models are determined by a combination of dice rolls and simple arithmetic. Though the gameplay is mostly based on medieval warfare, it incorporates fantasy elements such as wizards, dragons, and magical spells.
