Saganami Island Tactical Simulator ("SITS") is a tabletop wargame set in the Honorverse, a series of military science fiction novels written by David Weber and others and published by Baen Books.
 The first edition was based on the "" game engine, whereas the second edition featured a rewrite of those rules.
 Originally published in 2005 by Ad Astra Games, the second edition was published in 2007, and is based on their later released "Squadron Strike" movement engine, which uses whole turn pre-plotted movement, rather than segmented movement and time keeping.

Christopher Crawford (born 1950) is a computer game designer and writer.
 He designed and programmed several important computer games in the 1980s, including "Eastern Front (1941)" and "Balance of Power".
 Among developers he became known for his passionate advocacy of game design as an art form, founding both "The Journal of Computer Game Design" and the Computer Game Developers Conference (now called the Game Developers Conference).
 In 1992 Crawford withdrew from commercial game development and began experimenting with ideas for a next generation interactive storytelling system.
Marco Alberto Donadoni (born in Milan, 8 November 1951) is an Italian game designer.
 He designed his first, self-produced wargame, "Iliad", in 1977; he then joined the Italian company International Team (IT), that at the time was mainly a jigsaw puzzle producer.
 IT published "Iliad" and changed its core business, focusing on the wargame market, with Donadoni being its main game designer.
 Between the late 1970s and the early 1980s, Donadoni created a number of games for IT, some of which, like "Zargo's Lords" and "Kroll & Prumni", were very successful and largely contributed to popularize wargaming in Italy and other European countries, such as France.
 Angelo Porazzi, designer of "Warangel" (one of the most popular Italian wargames of recent years) has often cited Donadoni's work as one of his major sources of inspiration.
 Donadoni remained as IT's main game designer until the company went bankrupt in the late 1980s, designing more than a hundred games.
 After that, he collaborated with several other major Italian game companies such as Editrice Piccoli, Editrice Giochi and others.
