It is not about killing EVERYBODY in the game,
Well, for some people, it seems to be. The issue here is that Larian is wasting a terrible amount of energy for a few people, while some basic stuffs will be missing.
but Larian want to give the opportunity to the player to deal with the quest the way they want, some players might want to kill a specific NPC, some others will have a disagrement with another NPC and will kill him and so on so on,
Yes, this is truly nice. No sarcasm inside. I really think this is great, especially in multiplayer (which I probably will not try, anyways...)
the point is to give the players the opportunity to play the way they want with a complete freedom
Here I don't agree. No night stalking assassin, obviously. No waiting for the night to try to sneak past the orcs ...Day stalking psychopath bully, for sure... So don't talk to me about complete freedom. This is a computer RPG utopy.
