I know I just appear occasionally in this thread to vent / seek moral support but... Well it's time again.
I think, and I don't really want to vocalise this, I just don't like my group. Historically I've always run games for friends. Gaming with people I wasn't already friends with is a fairly new situation for me as being recent in the area I thought gaming might be a good way to meet some people and also keep a foot in the hobby. So I advertised a game and joined up with a semi-existing group. Don't really socialise with them outside the game. I'm currently GM'ing.
I mentioned this in a previous post that I'm the oldest in the group and two players in particular are noticeably younger. Previous session one of these was merrily torturing captives for information (unnecessarily, simple intimidation would have done it but they went straight for maiming). They steal everything no matter how petty. The campaign isn't focused around heroism but when a mission is to pull off some big score and players are trying to nail down things worth little cash it's just... Honestly it feels like someone running round a video game smashing open containers in the area they pass through to pack everything in their inventory. But it's the sadism and reckless disregard for consequence that mostly puts me off.
I can add consequences for their actions. But it's going to take the campaign down a path I didn't plan and wont enjoy. Sure, they can be arrested, sure I could run adventures set in prison, sure I could have revenge squads seek him out and run adventures where they're on the run or have to defend themselves, etc. But it's just going to make my campaign about endlessly circling the drain, never getting into the grand adventure and high stakes I have planned out. Just a treadmill of stupidity and consequence.
But I think it's the cruelty that bothers me the most. The pettiness and disregard for consequence close behind.
Sometimes its best to just walk away.
Gaming life has been so much better since I fired my problem players. Yes, it'd be nice to have more than two players, but trying to manage the problematic ones was just a constant waiting for one of them to flip out, and its been such a relief to not have have to keep waiting for that.
In my games, torture (beyond intimidation and a little smacking around) is always fatal - "the (usually injured) person you were torturing goes into shock and dies when you break their arm" "You go to cut off a finger, but they flinch, you nick an artery/cut off their hand and they bleed out in seconds" "the holy water burns of the necrotic spell animating the wight and it is now just a corpse". Homey don't play that shit.
I'm assuming you've already talked to your group.
Other than people being mature and playing along - which is hard when they aren't in the minority and everyone else is doing shit -
The only times I've seen needlessly sociopathic players get reformed is feeding them their own medicine. Prison is just more fun adventures, but suddenly having their shit stolen makes them realize how much having their shit stolen sucks. And that's an iffy problem, mostly the sociopaths just get bored and stop showing up when consequences happen and they don't get to live out their twisted power fantasy.
One guy I read about had his players get elevated to petty nobility, gave them a town and peasantry. He let them plan out and start building their keep, get involved in town business, basically got them to care about shit with tax income as the foot-in-the-door.
and then had a band of Orc adventurer-equivalents come through and raze the place while the players were away, killing nearly everyone in horrific ways. The players naturally went out for revenge and got it, but having cared about their own little town of NPCs made them stop being assholes to everyone they met in the game world because they would be reminded of one of the peasants they liked.
But to me, that's a lot of effort on something that might not work. I'd just drop the group and get the contact details from the one or two you said you liked, then try to find players who aren't weirdos.
That or just get them over to something OSR where characters get murked on the regular, so the guy they are torturing turns out to have had Blood Rot, and now their character has Blood Rot and is losing 1 max HP per day.
