I accept the vast majority of NPC suggestions from my players, in part because I can't recall a single instance of a player-proposed NPC that was even vaguely problematic. I frequently prompt them to give me NPC ideas, in fact. One player invented a friend of his character from before he joined the military, a child of a family of jewelers that had gone through some hard times but were now back on their feet. (This was an explanation for a Spout Lore roll.) It hasn't come up since, but it was a thing. Another player invented Rahim, the suave-as-heck head of the Silver Thread, a Robin Hood-esque organization of ne'er-do-wells who act to support the common folk and limit the power and influence of the merchant-princes. Rahim has been a repeat character, and is actually a pretty powerful figure in the city....but that also means he is tied into various responsibilities and networks of power, so he's very helpful but not an inexhaustible resource. He likes to always meet with the party in a completely different secret room, and offer them lunch (or dinner, depending on the hour; he's never met them in the morning, and I kinda think he's not a morning person.)This is a bit tangential to the issue, but how do my fellow ENWorlders handle NPCs authored in by players?
I've found that player retention over family and "friend" NPCs can be useful for relieving DM strain, but quickly becomes unfeasible if said NPC supposedly has access to goods or services which the player desires.
