Man, the Tully's are douches with a capitol bag now.
I've played three games with the new version, two Clash of Kings one Conqueror. In the CoKs, both times the Tully's screwed me with factions to install Sansa as Queen in the North. Never mind that she was a minor, a girl, and a prisoner in a foreign court, nor that Edmure Tully is the Young Wolf's uncle and our relations were +75 the last time he backstabbed me. He waited till the worst possible moment too, I'd finally started making headway against the joint Lannister-Tyrell doomstacks (kudos on that BTW, made the war much more interesting) AND Sweetrobin Arryn finally died, leaving bold young Harry the Heir free to bring all the untouched strength of the vale into the war. I'd sent Balon Greyjoy home with his tail between his legs (err, tentacle between his other tentacle, being a Kraken and all) and I was marching my host south, to meet up with the battered remnants of my Riverland force, both set to join the mighty army the Vale was marching in to save the day.
This was the moment Edmure Tully saw fit to screw me by demanding Sansa be made Queen. I refused (as I was pretty sure that would instant-lose me the main war) so he not only took the whole Riverlands army with him but also got the magical bonus troops that faction revolts tend to get. So now I was dealing with about 40k Riverlanders marching up the Neck. Ragequitting ensued. I mean really, wtf bro? That's no way to treat your badass nephew.
In my conquest game, I installed Orys Baratheon as Lord of Harrenhall and LP of the Trident (not being able to get him the Stormlands, as the Storm Princess married), and the Tully's just kept managing to depose him. Even when I wound up imprisoning virtually the whole family and executing or sending them to the wall, there was always one survivor who was always able to round up a conspiracy able to oust my half-brother (then later uncle).
I think a hard look has to be taken at how the new features in the main game are interacting with the mod. On the upside, I can now finally start/join a conspiracy to install Dany as Queen. Looking forward to trying that one.
