What would be cool would be if you could multiplay and have your friends command units in the same army. Then you could have realistic subcommanders who would actually make human decisions... Of course you would run into problems if you get people with different ideas, eg. if your mate with the cavalry goes charging off after some routing units when you [I]really[I] want him to come and charge the rear of the units you are locked in battle with, but that sort of thing happened historically too!

I can but dream...
