What's your take on the depiction of violence in these games? I've played a lot of sports games, and to my memory they frequently gloss over the implementation of injuries to players for gameplay's sake. They don't want a team's season decided by a random, season-ending injury to a key player - realism is deliberately subverted in the interest of gameplay, because when we're playing a game, we don't want sheer bad luck to ruin everything. This is especially true in multiplayer games, where having a whole season combust because your ace starting pitcher cut his pitching hand while gardening would seem outrageously stupid, but I've played single-player sports games that gingerly dance around realistic, random player injuries ("wear-and-tear" injuries are more common, because those are something the player can plan for and control).
Likewise, every wargame I've ever played grants the player near-perfect command & control. Again, this is in the interest of not frustrating the player. Having units fail to receive your orders, or show a delay in getting and implementing your orders, or be unable to carry them out for reasons you don't understand, would infuriate most gamers. Some games implement a half-hearted "morale" system, but some don't even bother. In Company of Heroes, your men could be pinned, but wouldn't retreat until you told them to, and when they did, they did so in good order and quickly found their way back to your base so you could redeploy them (occasionally, a retreating unit would take a bad route, but that was usually blamed on poor pathing by the programmers and was never cited as 'realistic' panic and fog-and-war on the part of the fleeing men). In the Total War games, I don't believe you ever lose control of a unit that loses line-of-sight (signal flags) and the ability to hear audio cues (horns and drums) from the command unit. Game designers simply presume that gamers don't want even semi-realistic command & control.
p.s. I had another thought: How many men do armies lose to disease and desertion before they ever reach the battlefield in wargames, such as the Total War series? A line of female samurai would be a lot less strange than the miraculous health and fitness of the soldiers in these games, which we tend to take for granted. James Stavridis was on the radio yesterday, and said something like, "amateurs talk strategy while professionals talk logistics." Has there ever been a wargame where the soldiers' footwear and access to clean water were a concern?
