Hi Simon. I own a FT, Wh20, TS and aquired a BSD a few months back. In my opinion it would fit in with those other titles very well. It is one of the most challenging games I have played and for that reason I love it, I really feel like I am improving as a player when I play it and you cannot flail at all. It doesn't have the big wizard mode pay off at the end, but you have enough games that do that, variety is the spice of life. When you play for a while on BSD it really feels like you have earned it. If you haven't already seen it, check out Bowen's tutorial, definitely worth a punt in my opinion
