Project Nemesis is a fan driven website for games that use the One-Roll Engine (like Nemesis, Wild Talents, Reign and Monsters) or Chaosium's Basic Roleplay System (BRP) (like Call of Cthulhu) and the Delta Green setting.
The following is a pseudo-medieval city statted up for Reign.
The City is assumed to have some ruthless and powerful government --
whether that is an autocrat, a council of schemers, a theocracy, etc.
is up to the GM. The City Government has access to a certain number of
assassins, but these are not battlefield warriors and thus are not
reflected as a Might score.
I started statting up some of the Guilds and groups in my game. In
Reign, groups have five stats that define them. The PCs are the
Musicians Guild, and the first big plot will be a three-way struggle
with the Traffickers and Sages over the Performers, but the Butchers
(the dirty jobs folk) and the Weavers (a politically scheming group)
may get involved as well.
I am working on running a Reign game in which the players will be
running criminal characters attempting to cut out a space for
themselves in a big trade city. Right now I'm trying to come up with some interesting personalities and
Companies.
While I was doing some random planning for my Band of Bastards game, I
happened upon the Stoneheart Guardians and seeing if they had anything
I need to help fulfil my purposes. They did. They’re surprisingly cool
but what always turned me away from them was their entrenched monastic
lifestyle.
I've built a simple Reign Company generator.
I write for me so the interface sucks but you can cope the same way I
do. By default it rolls 10 dice. Change this with the dice paramter.
Rum & Bones is an organization based around the galleon The Pearl, a
bastion of gambling, drinking and whoring just off the shore of the
city of Marsui. Rum & Bones' Goal is to Dominate the Underworld of
Marsui. We pictured Marsui like a colonial New Orleans and its city-state
rival, The Keys like the tip of Florida with the Corsair's rocky
islands in between.
For playtesting and demoing, I set up a thing I
called "Imperial Harlots" in which the players have characters, but no
stats because those characters are the five people who really run The
Empire (okay, The Empress is in charge, but to make this playable
instead of a game of "persuade the biased GM" the demo assumes she
takes the PCs' advice on everything).
