Distinctive Software Inc. (DSI) was a Canadian video game developer established in Burnaby, British Columbia, by Don Mattrick and Jeff Sember after their success with the game Evolution.  Mattrick (age 17) and Jeff Sember approached Sydney Development Corporation, who agreed to publish Evolution in 1982.  Distinctive Software was the predecessor to EA Canada. 
Distinctive Software was best known in the late 1980s for their ports, racing and sports games, including the Test Drive series and Stunts .
DSI also made sports games like 4D Boxing , and the second title in the Hardball series, Hardball II .
In 1991, DSI was acquired by Electronic Arts in a deal worth US$10 million and became EA Canada.  
In 1989, programmers Pete Gardner and the "Old Kid" (Amory Wong) of DSI, under the pseudonym USI (Unlimited Software, Inc.), converted Sega's arcade game Out Run into a DOS version. For Out Run, they used several software libraries they had developed for Test Drive II. Consequently, Accolade charged that DSI violated a working agreement, and sued. Accolade sought a preliminary injunction against the distribution and sale of Out Run. Distinctive Software argued that it had only used source code that did routine functions, such as clearing the video screen and that Accolade did not own a copyright on those functions. Accolade argued that their contract for Test Drive II gave them the ownership and copyright of the final product—the game—and the source code used to create it. Distinctive Software won; the court ruled that "the licensing agreement transfers to Accolade the copyright to the concept and design of the video game but not the underlying source code." The court also found that Accolade had failed to demonstrate that the balance of hardships was in its favor.

Homebrew, when applied to video games, refers to games produced by hobbyists for proprietary video game consoles which are not intended to be user-programmable. The official documentation is often only available to licensed developers, and these systems may use storage formats that make distribution difficult, such as ROM cartridges or encrypted CD-ROMs. Many consoles have hardware restrictions to prevent unauthorized development. A non-professional developer for a system intended to be user-programmable, like the Commodore 64, is simply called a hobbyist.
A video game clone is either a video game or a video game console very similar to, or heavily inspired by, a previous popular game or console. Clones are typically made to take financial advantage of the popularity of the cloned game or system, but clones may also result from earnest attempts to create homages or expand on game mechanics from the original game. An additional motivation unique to the medium of games as software with limited compatibility, is the desire to port a simulacrum of a game to platforms that the original is unavailable for or unsatisfactorily implemented on.
