@Imperious:
Pay 6 IPC gain one MP… heck id rather buy a sub for that or 2 infantry or half a bomber… or?
1 extra movement point would definitely alter the game somewhat, because one would be able to affect one’s opponent’s fleet maneuvers, say if he wanted to position subs and/or destroyers.
I think that the simple expedient of putting the ports into the game from the beginning with the +1 movement rule would be nice. So every power would start with at least 1 port, and some would start with several. But building a new port during wartime would have been quite difficult for most of the nations, (I’m talking about the fully functioning ship-building, ship-repairing, aa-defended, kind of port.) so why even have a special piece for ports? Why not just add the +1 movement point ability to any IC which can build naval units? This would make building ICs a little more attractive for the 15 IPCs which you must spend.
