What? Help… ally? In a Paradox game? What is this strange new world?
Welcome to the release of a major content patch in a Paradox game. 
[x-posted from the game sale thread]
In celebration of its three-year anniversary, Crusader Kings II is free to play on Steam for a week. These things usually only take place over the weekend, but in the case of CKII a week seems to be just about the right length of time to get the hang of things. The base game and DLC is also 75% off for the week.
All Game of Thrones and ASOIAF fans (and strategy game fans) should get the GoT mod for CK2 – it really is awesome. The game captures the backstabbing politics of the show and book series better than I thought any game possibly could.
Play as Robb Stark and try to marry Daenerys and kill Joffrey. Play as Stannis and win the Iron Throne and kill Joffrey. Play as Aegon the Conqueror and claim Westeros (and there will probably be some minor lord named Joffrey you can kill, if you want).
