Strategic Simulations, Inc. (SSI) was a video game developer and publisher with over 100 titles to its credit from its founding in 1979 to its dissolution in 1994. The company was especially noted for its numerous wargames, its official computer game adaptations of Dungeons & Dragons, and for the groundbreaking Panzer General series.

A wargame is a strategy game in which two or more players command opposing armed forces in a simulation of an armed conflict. Wargaming may be played for recreation, to train military officers in the art of strategic thinking, or to study the nature of potential conflicts. Many wargames re-create specific historic battles, and can cover either whole wars, or any campaigns, battles, or lower-level engagements within them. Many simulate land combat, but there are wargames for naval and air combat, as well.
