Is it just me, or is it too easy to form Alliances in the game - and thus to win the Alliance/Diplomatic victory? In each game I've played so far, just being peaceful and trading with everybody, and keeping a decent military while not being too aggressive seems to bring darn near everybody to "Close" relations sooner or later.
I know there's a bit of skill involved in doing that, but it still strikes me as kind of easy and anticlimactic. And that the AIs don't seem to value "he might be a threat to win" enough in alliance choices. Or did I just have some atypical early games, and it's usually more difficult, or the enemies more cantankerous. (Do they "break" alliances much?)
