2 hours ago, VikingWolf said:They did calm down later in the adventure, but when they did kill NPCs (although the ones they killed weren't vital to the story) it was done in the manner of their characters. For example a Twi'Lek opened the cell, gave them their equipment. One of the player's characters was very paranoid and didn't trust people, so he turned on her as soon as she gave him his stuff. So it wasn't total random killing all the time.
Sounds like definite D20 mentality to me. The "NPC's don't matter so let's kill them all" kind of sociopathic reaction most gamers have. I know you say it was "in character" to kill the twilek, but then when you follow that with "and they killed everyone", that tends to lean more towards the "murder hobo" kind of player mentality
What I do with my players, is try to stress that the story is paramount, not the dice mechanics or the loot. That the idea is to create a fun story with the narrative friendly rules, and not worry about the fine details like looting every body for all of their valuables, etc. I have one player, that even after close to 20 years of gaming with me, still thinks I'm out to kill him and the other PC's in every encounter. Despite my repeated statements that "killing you means the story is over, so why would I do that this early?" And my repeated stressing that I don't give a **it about the mechanics, and only see them as a tool to tell a fun story, and that I want THEM to do awesome, dramatic, cool stuff so that we all have fun, and it's an amazing campaign. And yet, STILL, he thinks I want to pile the corpses of the party in some altar to my GM a**hattery or something. *shrugs*
But I always stress that I want them to think of themselves as being in Star Wars, and the crazy, dramatic, heroic stuff the characters do. Like, leaping out of a window in a building 3 miles high, just to grab a little probe droid. Or diving out of a speeder at the same elevation, without a chute, to grab a passing speeder, etc etc. Go big, and have fun. And don't worry about the details of little things. That seems to help my players shake the dregs of their D20 mindset, which, I feel, is directly contrary to truly enjoying this system. It's more narrative driven, not mechanic driven. And for some players, especially coming off D20, that's a hard pill to swallow.
