SSI published the Panzer General series and the official video game adaptations of Dungeons & Dragons.

Chuck Kroegel, who joined the company as an employee in 1983, was the co-author with David Landrey of many of the early SSI wargames and led product development for over ten years.

Although the name implies action titles, it was in fact simply a branding of games being written by third party authors.

[2] SSI had expanded into role-playing games in 1984 with titles such as Wizard's Crown, Questron and the Phantasie series.

In 1987, SSI acquired the Advanced Dungeons & Dragons (AD&D) license from TSR and subsequently published 30 titles in that series, starting with Pool of Radiance in 1988 and including War of the Lance in 1989 (Apple II) and 1990 (MS-DOS & Commodore 64).

Panzer General was a very approachable and easy-to-play game that nevertheless had some gameplay depth and the sense of continuity and goals.

As the newer versions were released over a three-year period they increasingly became outdated in terms of improving computer hardware.
