Haha, no problem. I think it's a bit of folklore that is really specific to the region where I grew up. But I like it really much as a setting, exactly like you said: a bit of a darker Robin Hood 😉
And how to handle it when things go off road? Well, I figured not to plan out too much when the raid starts to keep it in the OSR-mindset. And let the players and GM decide how things go. I only provide an example of how things could end. But yes, the planning ahead may be a bit more like Blades in the Dark then Knave. I agree.
PS: I have run a campaign in a BitD type of game in the past and I love to run Call of Cthulhu and World of Darkness. So much of the inspiration will come from games like that.
