Another point for players of tactical wargames to consider was the increasing amount of unit data that was being built into the games. Rather than pieces depicting generic "infantry" or "cavalry" units as in Civil War strategy games, for example, games like "Tobruk" were inundating players with tables of complex ballistics information. "Firefight" came with a separate booklet on "Reference Data" amounting to 20 pages of information, much of it not immediately necessary for gameplay but certainly useful to defend some of the design decisions which restricted game play.
