Distinctive Software, Inc. (DSI), also trade-named as Unlimited Software, Inc. (USI), was a Canadian software house established in Vancouver, 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, with whom they worked closely.

DSI became known for various titles: 4D Boxing, Stunts, Test Drive and Impossible (1991), but also the second title in the Hardball series, and The Cycles: International Grand Prix Racing.

In 1989, programmers Pete Gardner and the "Old Kid" of DSI, under the pseudonym USI (Unlimited Software, Inc.), converted Sega's arcade Ferrari Testarossa game Out Run to its well-known PC-DOS version.

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.
