I just played a short game. I am liking what I see so far. Some feedback:

1) Love the new fonts. They really make a difference. Everything looks and reads nicer.

2) Love the new game options screens (customize opponents, etc.)

3) Tactical battles seem a lot better. Weak enemies actually run away etc. Nice.

4) I dropped my taxes to none and it still said 5% unrest because of taxes on my city. I understand it may be that way because of balancing but it should be called something else not "because of taxes".

5) There is something wrong with diplomacy effects. I met Kraxis. We both had 1 settlements. He had a stronger army and higher score than me (24 vs 10) yet his diplomacy screen said: You are dominating me (+5).  Clearly he had the upper hand so there is a bug there.

6) Monsters attacked and razed my only settlement (I also had an outpost). I still have my sovereign but no way to create a pioneer and I can't resettle for some reason (all fertile tiles disappeared). Isn't the game supposed to end? I suppose I can try to conquer another city but I thought the game ended when you lose all your settlements. If so, there is a bug there.

I'll add more as I play.

Overall, nice job!
