That's right you boys and girls yet another game developer going that extra mile to reel in PC game pirating. All new Ubisoft titles will require a CONSTANT internet connection to play and save the game. All game save data will be stored on Ubi servers and if your connection drops out, well your game pauses and you wont be able to save. Looks like Far Cry 2 will be my last Ubisoft game. Bastards.
