But that rarely seems to how child NPCs are used by players. It usually seems to be some sort of house-RP wish-fulfilment fantasy and I really don’t like being a part of that
Interesting. That does all sound pretty annoying, but that hasn’t been my personal experience. I wonder if it just comes down to the types of games or specific players or something. When I’ve seen child NPCs used, it’s usually been for a specific plot point. When I’ve done it, either been for that or just because my character happened to be a parent. Almost all of the times were after I myself was already a parent, so there definitely wasn’t any wish-fulfillment going on. It was just exploring an aspect of the character that seemed interesting to me at the time.
I remember one amusing scene where @Roadspike’s Viper pilot was getting grilled by my character’s NPC kid. That would certainly become tiresome if it happened all the time (for me to play as well as for everyone else to deal with), but the kid was largely off-camera with his grandparents. As occasional flavor, I think he brought a bit of levity to scenes, while also highlighting who the PCs were fighting for. It also added depth to that character, who was struggling to balance being a single mother in a war.
YMMV of course but that’s just my experience.
