I won't be buying the expansion until I have concrete evidence that the AI is no longer the abysmal mess that it currently is. I really hope they have made it so that the AI can actually do war. By this, they need to be able to use artillery, Aircraft, anti aircraft and the navy. None of which they do AT ALL currently. All of my games work out the same. If a civ gets ahead in tech or culture, go to war. 4 Bombers and a tank is all you need and you can literally take EVERY city on the map and there is nothing they can do about it. There isn't even a downside as all they can do is denounce. This can't go on. We also need ways to stop/prevent or threaten CIVS who attack city states under your wing. Currently, you can't do a THING about it. There is also no option to ask civs to make peace in wars with others. Seriosuly, instead of adding more complexity to the game, they need to get these basics right first.
