Games and History Part 1: the Fog of War

I recently received a "homework assignment" from the gaming group that I play with.  This consisted of a copy of Against the Panzers by Allyn Vannoy and Jay Karamales and instructions to read it with an eye towards what lessons could be applied to my tactics in wargaming.  Reading the book has indeed given me some insight into American infantry tactics in the second world war, but on another level, reading the book has given me insights into how history relates to games development to a degree that will require several posts to analyze.

One of the first things I noted with regards to game development and game tactics and strategy when compared to historical scenarios is the role of what has come to be known as the "fog of war", the limited information available to a commander with regards to the current situation, be that situation real or simulated.  The one thing that is obvious in retrospect when reading about the second world war is how little each side knew about the disposition and conditions of the opposing forces (and occasionally their own forces).

In tabletop gaming, its hard to represent the fog of war on a meaningful level without major investments in time and resources.  Simple board games can accomplish this by hiding the values of the pieces from the opposing player, but still intelligence can be gleaned from watching what moves where, and where the opposing player is focusing his attention.  More complicated games require a neutral party capable of determining when the opposing sides notice each other.  This adds complexity and therefore time to the game, and requires the attention of an additional gamer that does not get the satisfaction of actually playing the game.

With computer games, the computer itself is able to act as a fair, transparent third party.  This means that for casual gaming, the computer has an advantage over the traditional tabletop game as a means of providing a 'realistic' tactical model.  The recent staple genres of computer games emphasizing tactical decision making have been the real-time strategy (RTS) and tactical first-person shooter (FPS) genres.  Real-time strategy games generally emphasize an overall battlefield level of control, as the gamer directs units from an overhead perspective, and make decisions as to unit aquisition and overall strategy, while leaving the micromanagement of combat to the computer.  First-person shooter games have always put the player in the role of a single battlefield unit, and emphasize reflexes and situational awareness.  The modern tactical breed of FPS games adds the additional level of encouraging small groups of players to work together with a variety of roles in combat, where a balanced, coordinated team can effectively deal with larger numbers of uncoordinated opponents.

Real-time strategy games have almost always featured a two-level awareness limitation.  First, the player screen normally shows only a small portion of the field and the units under the players control at a time, requiring the player to shift his attention between locations.  Second, the information displayed is generally only valid for a short distance around the players units and their allies, meaning the current situation in a large portion of enemy controlled territory is unknown.  On the other hand, units in RTS games are perfectly coordinated;  what one unit can see is available to the player and any friendly unit.  Additionally, units in RTS games also have perfect friend or foe recognition, and will not target friendly forces unless deliberately ordered to do so.

FPS games have a different set of issues approximating the fog of war.  Normally, the player's visibility is the simulated line of sight from a single soldier or vehicle (although some games allow special extras, such as forward observation for beyond visual range artillery, remote sensors or camera-guided weaponry).  As the limits of visibility in computer games is a factor of computer power and screen resolution, this visibility distance is very short and of poor detail at distance.  Computer games tend to approximate this in some respects by providing a limited friend-or-foe system, but this tends to limit the realism of trying to identify a potential hostile.  In addition, to provide the fun expected by people who want the fun of a fast-paced game with friends, FPS games normally provide the player with a running casualty tally, indicating the casualty, the killer, and the weapon, often valuable information.
