A few days ago I spotted a small hardcover address book (the kind with A to Z running down the edge of pages and little bits cut out etc) for 68p in the supermarket. I guess it was reduced to that price because no-one has these anymore, all your numbers are in your phone and people don't send letters - at least, that's what the news says.
But anyway, I picked it up because I thought "Hmm, for things like my various LotFP games I could come up with a book of NPCs..." The idea being that I wouldn't just default to random tables as I typically do, but I would have a book of people. Maybe I would take one randomly, maybe if a player says "Do we know any journalists?" I could think Ah-ha! and look up Reg Cutter, the sleazy journo for the Wetham Herald... It might be fun.
Today I spotted a marked down diary. I didn't buy it because it was a pretty poor looking little thing, but afterwards it got me thinking: there are always events and festivals and special days in cities. When you add in religions and organisations then there are feast days and observances and so on and so forth. There is always something happening in the background.
So: how about a book with 365 days of festivals listed? Some religious, some street things, some business, some cultural. Potentially adding nothing more than a little flavour ("On 9th December, watch out as children run through the streets with strings and ribbons to try and create a trap for Santa!") or maybe having mechanical effects ("17th July is the god Honarius summer feast day; Honarius is the god of winter and daggers, and those who make an offering before sunrise in his name will find that their short blades strike cold and true until sunset (+1 to hit for daggers, on a 3 or 4 re-roll as the blade freezes the wound)").
Perhaps this is something else to add to my Big List O' RPG Projects... At the minute it is just a little idea.
