I would suggest splitting the Hotseat Guide section in two based on Auto-calc hotseats and Played Battle vs AI hotseats. The two really aren't comparable except perhaps in diplomatic terms (But even then you can take a more aggressive line with a nation that stinks at auto-calc than you would in a game where they could fight it out, witness the GHC).

I'm no expert on hotseats, but I'll try to collect my thoughts and put them down in an organized fashion.
