The Bringing Down the Pain “Group” rules from the Finnish version of TSOY, translated back into English. It’s worth noting that the guy who translated the game is also a very good rules wonk and tweaked things here and there in the rules, so seeing his version of the rules are really interesting and often enlightening.
At any rate, it’s not that his version of the Group BDtP rules are different than the English version, they’re just looking at the whole situation, and explaining it, from an very different angle (134 degrees rotated horizontally, 32 degrees vertically :). It might be useful to get your head around it.
