I've been thinking a bit the past couple of days about a game where the players take over a city.
Partly inspired by the Malazan books by Steven Erikson and Ian C. Esslemont, and partly inspired by the Kingmaker adventure path for Pathfinder, and maybe even a little bit by Ptolus (from what I can remember of it). Even a bit from the PC game Republic, if anyone played it.
I want to sit the players down, and say 'you're going to take over a city.'
The characters are drinking and playing cards and being merry in the backroom of a tavern in the middle of this sprawling mess of a city, full of corruption and waste, a hive of scum and villainy and whatever. They have decided, after many years, that they just can't take any more, and are out to conquer the city.
I might get them to give me a bit of a brief for the city itself, but I've got my own ideas too. And then see what kind of characters they make. Maybe they're all guards, and they want to take the place back from crime. Maybe they're all war veterans, and they're going to stage a coup. Maybe they're all criminals, and want to run a new cartel.
Whatever happens, they'll need to secure a base of operations, work up some grass roots support, and maybe infiltrate the higher echelons too. And then of course there's rivals, other threats from other power players who want to keep the status quo, and maybe threats from without too.
No clue what kind of rules I'd run. I imagine that a good setup would have a relationship map and a few hooks onto locations that the players can interact with, so I might rip an entire section out of the Smallville RPG for that (is it in other Cortex products too? I've only seen Serenity and BSG).
Maybe the City of a Thousand Temples would be a good setting for the game? I'll keep working on this. Feels like it might be a winner for actual play.
