Crusader Kings 2 [official site] is a grand strategy game about human beings instead of armies, and it spins gripping Shakespearean yarns about medieval social climbing, full of murder, betrayal and bastards. It's brilliant, but you might be a little intimidated by its setting. That's just one of the reasons why the Game of Thrones mod is so good - and it's just hit version 1.0.
The Game of Thrones mod switches the game's real world setting for Westeros, and switches out its nobles and royals for the nobles and royals of the Song of Ice and Fire novels. That means you can take control of Ned Stark and try to survive, or any of the more minor characters in any of the series' houses of assholes.
It's been a great, polished mod for a while, but version 1.0 brings finishes "integration of World of Ice and Fire" material, improves the White Walkers and otherwise rounds off the package. It doesn't necessarily mean the end of development, but it's everything the developers wanted to have in for a 1.0 release. There's a full changelog at that link above.
