Fable 2 allows you to craft your own epic character as well as do a lot of things that have no real point.
However some shots with over the top HDR and fields of flowers truly are breath taking. Truly immersive and beautiful. If I die ending up at the level "A perfect day" would not be a bad way to spend eternity. Another plus is that the game is funny. Especially some of the item descriptions. Though I believe there could of been many more choices when it comes to items, clothing in particular. Though they're all useless, so maybe not. At least people who want to waste money can eventually buy them with the downloadable content.
Game play wise, you really don't need anything other then lightning throughout the entire game. It's nice to unleash a fully charged spell and take out a dozen guys. When I made my evil character, stomping through the slums, breaking down doors and slaughtering women while their children cried... It can be wickedly fun.
When the game constricts into a more narrative role I felt it was truly at it's best. Such as having to choose between experience and feeding prisoners. Will you be that cold? The choices you make during those portions having possibly astronomical effects when you return to the free form world. Brilliant.
This is definitely an RPG experience you should check out. It has no major flaws. As long as your copy doesn't freeze and force a restart that is. To Sum up, in the end Peter Molyneux did achieve his goal. I miss my dog.
