@Thenomain said in Difference between an NPC and a Staff PC?:
But what does that mean, "like a PC"?
Circling back to this one for a second...
In a TTRPG I think this is much easier to quantify because PCs have one or more other defining characteristics: complete character sheets, presence in every session as a core team member, gaining XP and loot on par with the other PCs, etc. Granted this may not apply everywhere, but it's reasonably universal.
But I think that the biggest defining characteristic for a PC in a TTRPG is that the player is trying to succeed. What "succeed" means may vary - get to level 20, complete the mission, kill the Big Bad, survive, whatever. But generally PCs have an agenda.
Players of NPCs shouldn't have an agenda beyond "play fair and tell a good story". Of course your NPC ICly has an agenda, but the minute the player becomes too invested in that agenda, they're being played like a PC.
(I will refrain from rambling on about my utopian dream that all players would go into the game with no agenda beyond "play fair and tell a good story". While that would sure be nice, even I'm not that naive :))
