AI (like many) tactical and in diplomacy you are not getting that 'oh my god, this AI is so dam evil and I didn't see it coming.'- situations. They did a good job giving you a stable and interesting game to play. I hope for a good modability and people who will be able to put some time into doing it.
So it seems, that there is room for improvement. What seems good is, that there is a fanbase and they try to make this people a part of their team.
