I for one am pretty excited about the little pooch. I think it's a fantastic idea; it reminds me a lot of The Bard's Tale. Even in death that dog was all about helping you kick ass and digging up treasure for you. But maybe you don't like dogs. Maybe you don't want that adorable, loyal friend tagging along with you all over Albion. Well, that's fine. But you can't just turn him off. What you can do is leave him injured, whimpering and limping behind you. If you don't feed him doggy treats to heal him, he'll stay injured, which will slow him down. So he'll still be following you, but he'll be very far behind. And when he does catch up with you, you'll find him still injured, and still limping around, loyal to the end even if you abandon him, you cruel, heartless bastard.

Oh, and while we're on the subject of Fable 2, online co-op WILL be available at launch after all. It seems they're managing to get it out on time. I guess they just panicked before and didn't want to delay the game disc in case it wasn't quite ready. So when you pop the game in on launch day, it should immediately prompt you to download the patch.
