Based on Raymond E. Feist's Riftwar saga (and co-written with Feist himself) is Betrayal At Krondor, a new tale in the Riftwar universe. Exploration in a 3D world and turn-based combat complement the story, which is divided up into nine chapters. Each chapter has a goal to achieve before moving on to the next chapter, but how that goal is met is up to you.
