Downloaded, installed, and played for a while last night to get a feel for the mod. So far it looks like a fantastic mod. I played through a fast 100 years as House Clegane and didn't see a single crash.
I read too late that the mod is intended for the lowest AI aggressiveness setting, so there were a lot of little wars getting declared constantly everywhere, but otherwise it was great fun to see all the characters from the books. There's even a faction of wights led by Cold Hands up in the north, the Kingsguard, the High Septon, the Nights Watch, plus a number of events like The Great Winter.
The downside of course is that it has a lot of the quirks and issues that always plagued CK, but overall it's a really professional looking, well done mod.
It also looks like the author has been inspired by the new show on HBO and has been making improvements and updates lately and has promised a new scenario soon that starts around the time
