Jorune was the first game I remember deciding not to buy because I knew I would never find anyone to play it with. It "violates" the campaign setting rule of not diverging too far from what they players know. From what I understand (and seems confirmed above) it feels very alien and thus the player lack a solid point of reference for understanding the world. Even if you've never done it yourself, you know what swinging a sword is like, you know what riding a horse is like, you know what grass and trees look like, you can imagine the smell of a city sewer. Heck, even elves and dwarves are known to you. The strange alienness of Jorune seems to require too much effort on the part of the players to buy into the setting.
