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.
My bad, I did not stated my thought clearly. I meant you have a complete freedom in dealing with your quest by killing the NPC you want^^
I really like rogues sneaking around, hidden in the darkness of the night, and this is a real shame that Larian cannot come up with the night/day schedule (even with sneaking/fight bonus) and I really hope that it will be added (or modded) later. Bit for the time being, I don't diss the work Larian did on NPC's and quest because this is another interesting and complicated feature !!
