I've being part of a fairy tale, a beautiful soundtrack accompanied me through the deep character creation, with detailed menus and explanations according the lore, I can even use my own portrait, learning its mechanics almost without noticing while I play.
There are plenty of text well integrated as a book with illustrations and choices based on your character's abilities, the best way to narrate great amount of text I've ever played, feeling really comfortable with my choices, also I've noticed that my own background is dynamic, changing through dialogues, priceless...
The combat system is the best in RPGs, like Dragon Age Origins, the whole party will fight automatically but I can stop with the space bar in any moment to give individual commands, one of the most comfortable ways to manage parties.
And many more details as the exploration, construction and improvement of my own fort, strange visitors, imaginative side stories, surprises, random encounters... Sincerely the best RPG today.
