So been playing KoH again after a break.
What I have found, and I think others have noted this as well, is that there is precious little need to make any kind of agreements.
Every request for a trade agreement, break relations, attack a country, or even go on a crusade is automatically denied by me with little consequence. Sure, maybe the other guy may think a little less of me, or maybe even the Pope excommunicates me.
But I don't care. It really doesn't seem to affect anything. I just go merrily on my way. It's come to the point where I even start ignoring the messages they send me. Just right click on them and gone.
Just take my two armies and roll stomp every other country.
Of course, if I want to make things interesting, I attack the Papacy. That tends to get on everyone's bad side. Then I have armies coming from everywhere like ants. Other than that, though...
Definitely looking forward to KoH2. It will fill a hole that Total War has left since they abandoned the medieval period. But decidedly want more depth in KoH2.
