Strategic Simulations, Inc. (SSI) was a computer gamedeveloper and publisher with over 100 titles to its credit since its founding in 1979. It was especially notable for its numerous wargames, and for the groundbreaking Panzer General series.
The company was founded by Joel Billings, a wargame enthusiast. He hired programmers John Lyon, who wrote Computer Bismarck, and Ed Williger, who wrote Computer Ambush. Both games were written in BASIC as were many of SSI's early games. Computer Bismarck was released for the Apple II in January 1980 and for the TRS-80 later in the year.
SSI also expanded into role-playing games in 1984 with titles such as Wizard's Crown, Questron and the Phantasie series.
