villain of the story
Arcane
Sorry but the on-rails approach of TW kills any illusion of 'sandbox' to me. And really, comparing it to Bloodlines doesn't make much sense. The reason Bloodlines is praised here is because of its multiple character development/playthrough styles and C&C (two things the Witcher lacks in any meaningful quantity). Everyone recognizes Bloodlines has pretty terrible combat and mediocre level design.

How is Bloodlines not on-rails?
