I don't think it's a case of being bored with my farms, I'm not. It's more a case of looking for new challenges and planning ahead. I've started to run down some of the facilities I'm planning to move so, yes, I'm a little impatient for a new farm. I've stopped playing all the other games I used to work (some quite successfully) because of the fact that this game is so good now.
A new release is definately eagerly awaited here.
