What is Crusader Kings 2?
Crusader Kings 2 is a strategy game from Paradox Interactive, the makers of all sorts of grand strategy games that span a vast time period, from 1066-the late 20th century. In this case, we are playing their game focused on Europe of the Middle Ages. Specifically, the second of those games. It's probably the best, or at least the least buggy, game they've made. In it, you take control of a dynasty, not a country, and try to guide them as successfully as you can to rank with the great families of history.
What's a Succession game?
For those of you who didn't participate in either the Civ4 succession game or the LP Paradox thread (that sadly crapped out with us all powerful in the 18th century), a succession game is a game where a number of players take control in succession. In Paradox games, that will be when the current ruler dies.
Short and sweet.
