In cities and towns, guards should rotate on day and night shifts and also patrol around town constantly.
To explain it best, a bit like how soldiers patrolled around in Assassin's Creed.
Also, the guard for the dungeon should change at the same time. Apart from cosmetically looking nicer, and making the game look more living, this could have a small game effect like maybe certain guards will attack you if you try to bribe them, maybe another one will offer you a cheap bargain, depends who you get. With this, you can help a lord escape prison, or enter lords hall for cheaper, or have to fight your way out because you bribed the kings guard!
Also there could be certain roads or places guards ignore or don't enter, the thugs could be located here, as they are out of the way.
