First, for all those wondering how to get those million score points, don't be in a hurry to see how fast you can accomplish your 4 goals. It seems that around 200 turns with max food and max happiness is the optimum point to finish your game.
Second, the game seems designed to prevent you from conquering all city squares until you have obtained at least 1 objective. I actually found this to be a little irritating as you can spend 50 turns on 1 square with a lot of soldiers and never conquer it.
Third, outside of the drawback noted above, the game is quite an entertaining strategic game. It is one that can be played over and over again with differences each time. I also like the fact that it's not a real time game turn. Of course, as you get good at it, you need less time.
So that's it. I guess from here it's time for me to try your sequel. All the best.
