I've always liked the idea of having your own castle, as a sort base of operations in games (RPGs mainly, though other forms of open-ended games might work too). Some games feature this, the ones at the front of my mind are Neverwinter Nights 2 and Baldur's Gate II, but I was wondering whether some of you had other suggestions for game that feature this (castles, not houses), and what your opinion of it is.
