I thought there were only two?

But yeah, it surely is hundreds of hours. Very, very intricate, and kinda realistic. You don't need to eat or drink, but you have to sleep, you can only run/jump/swim so far without getting tired, you can vary how hard you hit by how long you hold down the mouse button, and you develop your skills (EG, Spear, Sneak, Athletics, Acrobatics, Long Blade, Mercantile, Heavy Armor) as you use them. It takes little time to learn the game's mechanics, but getting around can be frustrating from time to time. You'll spend a LOT of time wandering the wilderness if you want to find the really good stuff. Only so much is in cities. Its got a lot of options as far as what guilds/organizations you want to follow(I for one enjoy the Imperial Legion, but there are also churches, your generic theif/fighter/mage guilds, and the family-based "house" factions of the natives.), the classes you can take(you can actually make your own, in fact) and the creatures you can become (Vampirism or Lycanthropy appeal to you at all?

)
