We have been playing Here I Stand by GMT Games.

This is a thoroughly amazing multiplayer board game for first half of the 16th century. The history is amazing. The game-play is fairly easy, but the subtle roll of diplomacy and card play really make this game click!
We have six gamers playing next week. Our first full session was won by Brian Connolly (auto win for capturing enough keys) for the Hapsburgs!
I've been playing the Papacy, which has an entirely different set of victory conditions. I'm mainly focused on the Italian boot and burning heretics. Turning back the tide of Reformation!
