All I wanted from Fable 2 was another distinctly European-looking dark fairytale, but with a better (stronger) story than the first. What I get is a game with more incredible little pointless things smothering a core story that may or may not be good. I can understand why people with a lot of time to spare and with a passion for doing random things would love this, but it's pretty obviously not for me these days.
Same here. After Fallout 3 Fable 2 feels shallow in a lot of things. I played it till the end and put around 30 hours into it but the longer I played it the more abstract all this fluffy stuff appeared to me. Buying houses ended up being little more than clicking a sign. The combat is great, except for the way they make you use magic, making it difficult to freely use your full potential and variety of magic capabilities. The story was decent and it had some genuinly interesting dilemma, usually causing an effect on the appearance of your character, which was neat.
The limited/gimped map functionality blocked you from getting a cohesive mental image of the entire world.
Anyway, it was all a bit too 'simple' for me. I'm more into Bethesda's RPGs like Oblivion and Fallout 3, or something like Mass Effect.
I was satisfied, I didn't hate it but I wasn't wild either and didn't see myself ever coming back to it so I sold it. I do think it can be a good game for people not accustomed to RPGs or games in general, it's very easy and straightforward and has lots of neat stuff to dazzle the inexperienced gamer. A gateway RPG if you will.
