Use a single ship to check the coasts, put a single ship in a port in a country that is an ally or allows military access. Then you get the same view as a land unit with no attrition on the ship. From several provinces and sea areas, you can see and watch at least half a dozen or more areas with one unit.
In the land case, send a single unit into allies or countries allowing military access. March through barbarian lands.
If you are at war, the single unit loss is not to bad, and your enemy may not even be at war with your friendly nation.
As I recall , but it has been a while since I got them, trading rights allow you to see a lot of what is in a country too. That is part of why the computer is so clutchy about giving them away.
I know two cheats to accomplish the "I want to see everything", but you must work that out on your own....ponder the saved games files or the loading of saved games.
Please try to fight fair as the game is one of strategy and tactics. If you are really stuck, tell me a good joke. Then I will reveal all.
