Amazing game...addiction is already in place.
Yar. The attention to detail really is awesome. Wolves hunt deer etc, dialogue is much better (you can ask your henchmen about stuff that happened in the middle of the quest and so on), indoors areas look absolutely fantastic (outdoors too, but obviously not as good because of the huge drawdistance), guards might drop hints at a quest ("beware of bla bla on the east side of the river.."), Shouts are a fucking wonderful invention - not only are they cool as hell, they add a whole new layer of rewarding the player for doing dungeons and exploring (not just "wow, a diamond!" but "holy shit, it's a new Shout!").. some people have dissed the combat, but I think it's great once you get used to it. Finishers aren't frequent enough to bore you, when they happen they just add flavor. So much stuff to see on the roads, minor quests and new places and such. Also the, hm, transformation.. not to spoil too much.. really feels great, not just different visuals but the whole gameplay changes and really makes you feel like a.. transformed dude.
And there's so much moar. I'm a total fanboi now. This is the game I once dreamed Oblivion would be. Only better, much better. I can't even imagine how awsum it will be when the mods start rolling in.
