Like many of you I've been playing the TW series for years and I am still playing MTW: VI.

I have been planning to get MTW2 as my Christmas present to me (if Mr. Claus doesn't deem me worthy of it ;) ) and having read the patch wish list here and various other bug reports I'm left wondering:

Just what does MTW2 actually do better than MTW? What makes going to 2 from the original "worth it"?
