I was surprised when my dog, who I named Murphy and was fond of, sacrificed himself for me at the hands of Lord Lucien. It hurt a little bit. Each time I dig up treasure or open a chest now, I always miss having the dog beside me. After killing Lucien, I chose the option of wealth (being an achievement junkie, I cheated and got all three ending achievements by quitting out and redoing the short passage of gameplay). This meant I would not have my dog, but would have ONE MILLION gold to spend on whatever I wanted. This was all well and good until I realised that there was a money cheat and I could have saved my dog AND been rich. Too bad I guess. I'll have to play again and choose a different path, so I can see the dog again.
What really freaked me out though was the fate of Theresa. When Lucien was defeated, Theresa said I could rule all of Albion; BUT THE DARK SPIRE WAS HERS. She had previously shed light on the catastrophic damage that the Spire could cause, the evil it contained. What a sinister end for the "good" character in the game to disappear into her own sinister motives. I also realised later on that she may be up to something in the franchise's next installment, as I could NOT swim out to the Spire at all. THE GAME WOULD NOT LET ME.
All in all, I really enjoyed Fable 2. Having not played the last installment I didn't really know what to expect, but now I'm hooked completely. I have over 700G on it and I hope to get as close to 1000G (cant get the "Completionist" achievement due to lack of dog *sniff*) as I can.
Highly recommended, my full review coming soon.
