SIFRP/Game of Thrones/Ice & Fire
I was in a few games... they eb and flow. I like the setting, and wouldn't mind going ahead and jumping in on this if you find a GM. One of my favorite ones, was each player had a house, in the Westernlands, and we did deal with local politics. We had very interesting houses, from upstarts that got their lands in Roberts Rebellion, to an ancient House of First Men that were in ruins due to backing the Targarians during the war...
Each player RPed about 3-5 characters from their house. GM RPed Maesters, Septs and the like, as well as Lord Tywin, and his cohorts. Their was ALLOT of politics, scheming, and at the end, two of the houses (possibly three0 were at War, a political marriage in the works, and some other craziness. Wish the GM was willing to try and revive that game, it was awesome...
