In the 1960s,
Avalon Hill was the main board wargame publisher in North America, and released two high-quality wargames a year.
Jim Dunnigan, who worked for Avalon Hill, left to co-found SPI in 1969, with the idea of selling a lot of titles per year. In 1969 and 1970, the fledgling company published a "Test Series" of fifteen cheap wargames that featured photocopied rules, counters and maps, mailed to buyers in manila envelopes. These sold relatively well, supporting Dunnigan's business model, and the company turned to more professionally produced products called their "Simulation Series". One of the first of these was
Strategy I, created by Dunnigan, Stephen B. Patrick,
Redmond A. Simonsen and John Young. The company had announced their intention to publish this game in December 1969, but as co-designer John Young admitted, "
Strategy I has been likened to an unwanted orphan child with leprosy. From the beginning, it was such a monstrous task that no one wanted to pick up the ball ... There was so much involved in finishing the project, that it was always more productive to finish something else than half-finish
Strategy I." A large number of errors were found in the rules, and in 1972 SPI released several pages of errata and a second edition of the game featuring corrected rules. In a 1976 poll conducted by SPI to determine the most popular board wargames in North America by all publishers,
Strategy I placed 80th out of 202 games. ==Reception==
