Spies Guys. Use them!

Super cheap thing: Send some spies in enemy territory. You will see everything. They remove fog of war. Makes wars much easier if you know where all enemy troops sit exactly and in what amount.

Yes, and not just for when you are at war but in other cases too. For example, by using spies I was able to find out quite early on that a major faction on the other side of the minor faction that I spied on was waging a full-scale war on them and moving rapidly across the map. I started preparing my battle lines much earlier. Gives you a lot of recon reach. Major factions are harder to spy on, though. They will have a higher diff roll I believe.

Just discovered that spies parked in the cities of your friendly major factions can help you create political / civil unrest and give you intel. The intel can be viewed in the reports tab.

If you fail a spy card does it make the person you spied on angry?

I failed a spy check on a minor faction next door to me on the first turn then the next turn they declared war and absolutely destroyed me.
