Who's in for a dwarf fortress tradeoff game and make a real masterwork. We play an in-game season and trade off with a narrative on what happened? Rule suggestions?
For those who don't know, dwarf fortress is a free game: http://www.bay12games.com/dwarves/
Also they have a "reclaim site" mechanic now.
Losing a site, then sending a new crew to set up a base on top of an old treasure-filled ruin infested with monsters to send expeditions into could be fun.
