There have not been a lot of conflicts in which game designers were able to do their work, have their games developed, and publish them between the time that the war started transitioning from hypothetical to inevitable. Desert Storm is one of the very few, and was a popular subject for designers. There was a Gulf Strike module, and Strategy & Tactics' Arabian Nightmare just to start, and with the exception of Command's game, essentially redesigned after the fact, all were intended to predict results.
But how many predicted anything close to the historical results? Command's Desert Storm should be disregarded for that question, as it was essentially redesigned after the fact to be a Coalition walk-over, at least unless Godzilla and a division of time-shifting Nazis appear.
In a sense, Desert Storm was wargaming's chance to model an upcoming conflict and then judge our results in the light of history. But how well did we did do?
