Vengeful families on Skyrim

One new feature in The Elder Scrolls V: Skyrim can change your way of acting in-game. If you're used to killing NPCs that pisses you off in the game because they stuck you not letting you pass or something, know that in the new The Elder Scrolls V: Skyrim may have a family.
This implies that if you kill a NPC coldly without reason, his family may want a revenge and will chase you until you are lying on the floor rotting. That's right, the families of the NPCs will want to revenge the death of their loved ones.
 So it is better to act cautiously in Bethesda's new game that will be released on 11/11/11 for

 PC, Xbox 360 and Playstation 3. There are hints that this come will be also released as a 3D game for the ps3 and Xbox no word on the PC yet. Hopefully for all you Cinema 3D fans that can come true.
