Following a tweet from Fredrik Wester last week to this effect, Paradox Interactive officially announces the release of a Linux edition of Crusader Kings II, their strategy/RPG sequel. Word is: "The critically acclaimed title is the first ever game from Paradox to be launched on the burgeoning platform, and plans to bring other titles to Linux in the future are in the works. Crusader Kings II for Linux is currently available on Steam." Paradox also plans a live stream at 2:00 pm EST today on Twitch where Project Lead Henrik Fårahues will be showing off the game's multiplayer support.
