A. What is your favorite halfling PC you've played or played alongside or DMed for?
Played: Arnor Rumnose, barbarian, a crotchety hermit, who couldn't forsake the call of duty from his old military pal and got swept up in preventing a total coup of the royal family, taking them to sea, thrilled to leave civilization behind, only to end up having to traverse a massive island metropolis and wrestle with the anxiety that caused.
Played with: Milo, the explorer of a new land who was ever curious and going to catalog every new creature and feature he saw so he could publish an adventurer's guide. Naive and excitable in the way that creates fun situatuons for the table.
Kith: The rogue with a heart of gold, who realized the second that she had a family that didn't let her run away that maybe being a hero not just more satisfying, but also more fun than being a scoundrel. Convinced that she could singlehandedly take on the world.
2. What have you done with halflings in a homebrew world, or done to mod their place in a published world, that you're particularly proud of?
The second they encountered gnomes and realized they weren't alone in the world, went on a massive expansionist campaign over the empty lands, taking control of the primary river path through the continent, only to eventually end up having a gentle skub/anti-skub style schism that divided their nation in half, each side now doing everything they can to gain the economic upper hand over the other, while not tipping into outright hostility. Incredibly jealous/envious behind a gregarious exterior. The second they hear of some new discovery, creation, invention, they need their own version of it.
Third. What's an idea for either of the above that you haven't gotten a chance to use yet, or haven't finished working out?
Just last night, had a session zero where I'm finally getting to play Perrin Barrelchest, a Drunken Master Monk, who is going to take the lucky feat as soon as possible, to reflect the charmed life he has had where everything has fallen into his lap, aside from getting kicked out of the monastery he worked for decades to join. A lighthearted character who hasn't been a good fit for the save the world type campaigns I've been in.
