"Which kind of game would you use?"
Viewing post in Spare the rod, Spoil the child comments
As said in the description : Spare the Rod, Spoil the Child is intended for any RPG but was created with Monsterhearts (by Avery Alder) and Bluebeard’s Bride (by Beltrán, Kelly and Richardson) in mind.
I'm sure you can play it with OSR or FKR systems as well.
Personally, I would go with Monsterhearts. Maybe it's just because I really like this game! :) In any case, it should involve less rule-tweaking/hacking, running it as it is, which is always a compelling argument in my book.
