When scorpion arrives at his keep the guards are just standing there. What i like to see is that when I or Ghandi arrive, the guards says something to me. Like "Hey, how are you." or "Nothing happened here". But when the evil kampfer arrives they say "Stop!".
Offcourse it can be done with other creatures, like vicars. If you don't kill them, they start talking to you, or even better, starts healing you. And if you kill them, the start muttering about the evil kampfer* who kills vicars Also paladins, like protectors etc.. they should salut player paladins.
Just some more action between player vs creature would be nice and make the game more realistic.
*Could also put other player in here, but evil = kampfer
