Distinctive Software
Distinctive Software, Inc. (short: DSI) was a Canadian software house established in British Columbia by Don Mattrick and Jeff Sember, best known during the late 1980s for their ports, racing and sports games, distributed in most part by Accolade, whom they worked closely.
DSI became known primarly for three titles: 4-D Boxing, Stunts and Test Drive, but also the second title in the Hardball series, and The Cycles: International Grand Prix Racing.
In 1991, DSI was acquired by Electronic Arts, and became EA Canada (and a major component on the future EA Sports studios), in a deal worth US$11 M. This also meant a significant blow on Accolade, which lost credibility and market share in the following years.
