Yes! It's SO good. You will get addicted to going off into the wilderness just to fuck things up. And the side quests, if you do all the side quests, you'll see it's like you've bought 3 games. And the cutscenes, to die for.
Definitely buy it, you get your moneys worth. It's got good visuals, amazing cut scenes, an intricate storyline, numerous free will decisions that affect later events, a huge world, and enough side quests and monsters to keep you busy for ages.
