In my opinion, it is not natural for the skills that allow a person to design good games and the skills that allow a person to create a good rule book to reside in a single individual. Designing games is at its heart an act of synthesis. Creating a rule book is at its heart an act of analysis.
Technical reading is also hard, which can cause players to report that a rulebook is worse than it actually is.
A wargame is a playable simulation. A conflict simulation is another name for wargame, one that leaves out the two unsavory terms “war” and “game”.
