Stealing kills

[Ereshkigal]

I don't think it is immature to feel irritated about kill stealing. It is a matter of how you see the game. Most people play the game because they enjoy playing/competing with other people. So they are very aware that there is another human being behind the character and that's what makes the game meaningful to them. So I think it is natural to be pissed off if you think that someone isn't playing fair (even if there is no explicit rule about kill stealing).  I suppose there are some who see other players and NPC's on essentially the same level. That's fine for them I guess, though I don't think I would like to be like that. I'd rather be immature than dead, heh.
 
Also, if I were just looking for beautiful text or interesting puzzles, I'd rather look for them in better places!

If an NPC would steal a kill, then I would consider it to be part of the game. If a player steals one random kill, I would also consider it to be part of a game. But when a player stalks you and tries to steal every kill it can from you, then there is a human being behind that keyboard trying to ruin my gaming experience.

When they single you out and follow you around, then that becomes harassment and is punishable as such.
