I like gritty and grey + magic! Magic doesn't have to be all giant purple and blue lightning spells. It can be subtle, and the low-fantasy approach, where magic is grounded in real medieval 'science' and magick (like alchemy, theurgy, or astrology) is my fav as well. That being said, I like lush beautiful areas in games also, just as long as they aren't too cartoonish and surreal (like Fable, since we're picking on that game).
