Fable 1 sucked.
I mean, it was really great during the whole 8 hours i spent playing it. also it was extremely linear despite advertising, alignment never affected gameplay at all.
Fable 2 was better, I promise you. I didn't like Fable 1 either.
Also, to tell the truth, I want to see how the new plot will affect gameplay. Rather than a "you're a hero and need to save the world" scenario, it's a "you need to become the ruler of a continent" scenario. Plus, I want to see how far weapons have gone in Albion.
