Understanding Strategic Culture Through Games
Completely disagree.  Games are idealizations of combat that leave out some of the most important details.  Logistics and support are absolutely critical to any kind of force projection.  Politics and morale are also essential for success.  Hardly any games even attempt to expose such critical details.  Because of this they end up putting emphasis on speed and formation that may be removed from what is possible or what might be reasonably certain to work.  Possibly the best thing that games offer is the ability to contrast with the many details of any conflict.
