this is by far the best rpg ever created. And definately one of the best games ever.
you can chose to continue the main quest or you can go do some exploring of your own. you can roam the land exploring hundreds of ruins, caves , towns, settlements, forts. or you travel to the realm of oblivion(much like hell) and fight off monsters who are trying to invade your world. you can talk to people whom go about their daily lives, going for walks , eating , sleeping , working, socializing. From these people you can gain side quests that greatly add to the experience. The side quests in this game arnt just to go kill 20 lions or 1000 goblins like some rpgs. the sidequests all have a deep story and they all require you to do something unique. Example, reclaim someones home, turn a town against each other, expose a vampire (I said it), steal a ring from the countess of the city. murder the head of the city guard, investigate a haunting, find a girl who has gone missing in a town with very strange folk . Fulfill a prophecy for the end of the world to drive a town mad ;and the game gives you choices of good and evil to chose the outcome of these quests. This game is so deep and unpredictable, you dont do quests for money(you earn money, but thats not the reason you came), you do the quests for the fun of it, for the mystery , for the deep back story. the game even has books in houses and book stores that tell amazing brilliant stories that make you want to read. THIS GAME MAKES YOU WANT TO READ. I could go on and on all day talking about this game and talking about the hundreds of quests and the hundreds of hours you will spend doing them and exploring hundreds of places in the beautifully rendered landscape, but i will let you experience it all for your self.
