Yes I played with it....I understand all things about the game concept, it is you who dont get my point. You say you cannot make truces or alliances even in Holy War? The best example is the Crusades. Those nations who were involved in it, lived in peace before and after it. Its all about diplomacy.
So if you ask me Dominion is more like a strategical deathmatch.
I think a strategy game with a diplo system is lot better, than a 'go and conquer' game...
I like the idea that you can set up alliances in the editor at least.
