I agree SA is a nightmare, Gunboat or not, but then I've only played 2 World games (1 as SA unfortunately!)
As for commentary; as a graduate of School of War, I must say, the commentary really enhanced the experience, and I think since this will be anonymous, then I don't think it can do much harm. My experience is it is very enlightening and sometimes very amusing, as the commentators have no idea of the underlying diplomacy afoot, and on a world map, in my very limited experience, I think long term alliance count for a lot more than the standard map, as it's a longer term game with more enemies on every side!
I'm all for it.
So who hasn't joined yet?
