YOU CAN MANUALLY DECIDE YOUR ARMY'S STARTING POSITIONS?!
I was doing a campaign in Medieval II: Total War, when I found out you could manually position your units before the battle started; it took me 70+ hours of playing before I figured that out.
Needless to say, I no longer have to worry about my archers being slaughtered by enemy cavalry since I can just slap a few units of spearmen in front of them.
EDIT: I also remember that I found the "group selected units" button in the same battle; there's nothing quite like being able to withdraw your general and his cavalry with minimum hassle.
