There are some aspects of Bull Run which bother me. For example, being limited to fire only when in very close range, with rifles. The rifle max firing range (in the game) is something like 170m, whereas the muskets can generally do between 120-150m. I realize this is an "effective range" figure, but I'd like to be able to use the superior range of the rifles for something.
Men don't seem to suffer from disorganization fast enough, maybe that's me not noticing, but a open fire at and advancing enemy infantry line at 90m or so should disorganize them plenty, if not send them back entirely. As it stands, they usually can still deploy, move elsewhere, start firing, whatever, as if nothing had happened. They take casualties, the info bar progresses, otherwise, all is dandy.
