For the people who had trouble with the GoT mod, all you need to do is put the mod files + movie clip file into the mod folder, so you've got the folder that says "A Game of Thrones" and the movie clip file. Nothing else, and you should be good to go.

Speaking of my own experiences with the mod, I've been playing as Robert in the rebellion, of which my plan was 'run away from the Tyrells until I can link up with Jon Arryn/Hoster Tully/Ned Stark', then kick the [censored] out of Aerys in the Crownlands. In this mod, Lyanna survived, and wed Robert, of which we had 4 children, the awfully named Myles Baratheon and three daughters. Cersei married Hoster Tully for reasons beyond me, outliving her brothers and Tywin. Jon Arryn wasn't killed but instead died much earlier on, leaving behind a bloody competant if slightly fat heir, rather than a sickly incompetant one. Stannis became Lord of Storm's End rather than Renly due to me being totally meta, while Renly became one of the greatest generals in the 7 Kingdoms.
But what of the valiant Prince Rhaegar you ask? Slain nobly on the field of battle like Jason Mallister? Stealing away on Dragonstone to swear revenge and lead an invasion to reclaim his throne? Nope, he ended up in the service of some minor Vale Lord on the Sisters and got syphillis. I think Robert is probably happier with that ending.
