And players should get penalties for killing good guys instead of gaining XP.
Killing good guys and to gain additional XP as reward is ridicules!
What defines a 'good guy'?
- An old woman who is missing her little grandchild
- A fisher man who is fighting for survival
- A little girl who is playing with her Dog
- A father who is building up a new house for his family
But how do you know that any of these (except maybe a girl playing with her dog) are good guys?
Say, the father who is building a house for his family might be building it from sacred wood, or maybe on some elven burial site.
The old woman might be missing her grandchild because he ran away due to her abuse? Or maybe she's a witch?
The fisher man who was fighting for survival (from what)? Elves, dwarves, bandits, goblins, undead? What if he's done something to disturb those guys?
Don't be so one dimensional.
