Personally I lose immersion when NPC's go into the realm of hysterically stupid.
Such as in Oblivion where the merchants seem to hoard all their stuff, instead of selling it. I just sold you a bunch of armor, so why is no one wearing any? I know these people have the money...why? Especially the town guards. All the bandits and marauders have armor far superior to yours, and armies multiple times larger. Also with the main quest, the NPC's just got so stupid. The tactical decisions made...
Also, the Imperial Legion. The mightiest army, all slain by some local wildlife. Maybe this place going to hell isn't such a bad idea...
