I rented this game under the assumption that it was a standard turn-based RPG, and I can go right ahead and say I was wrong. Very wrong.
Fable is an action RPG set in the world of Albion, and your sister has been kidnapped, and you are taken in by the Hero's Guild. This starts your life story, and you must complete quests to advance through the story.
This game is somewhat linear in that there are not multiple ways to advance through the story, just 4 different endings. The non-linear parts are that instead of going straight for your next quest to advance the story you can complete a side quest. Similar to Zelda...but with less choices!
The visuals in this game are great. Fantastic lighting effects, realistic facial expressions, awesome scenery. And the sound compliments it perfectly.
