Friendship is Magic, and Magic is Heresy.
Indeed. It is a group game, and part of understanding that is not bringing characters into a group that can't work in a group.Other characters you might not want to bring to a group unless they are expressly okay with it:
- The lone wolf that does everything they can to not interact with the party.
- The kleptomaniac who has literally no control over what they steal.
- The 'evil' character who has no sense of self-preservation and will stab a dude in front of the guards barracks and then tell his mama, who is also the captain of the guard.
- The sex maniac, both 'lovable' and 'skeevy' varieties.
- Anything that is a meme
- LOL RANDUMB
Vengeful character who keeps a "people to kill list" and makes a big showy point of adding people to it when they slight him, but effectively does nothing about it in the short term? Fine. Amusing, even. Think early Arya Stark.
Vengeful character who skips right past that to murder NPCs or PCs immediately? Not fine. In the first case you're removing other player agency from the group narrative, in the second you're removing agency entirely (or attempting to - many attempts at a sneaky player-kill fail). Think Cirsei Lannister.
