文明霸業 - 王者再臨

You can skip the initial tutorial. Focus on leveling up your Lord using construction quests. It takes about 10 minutes, excluding loading times, to clear around 9 stages.

This point mission should take about an hour to complete. The gameplay isn't difficult and is the same as the demo in the ads. The rally point location is in my screenshot, so for those who don't know where it is, you can find the rally point to upgrade by going inside the city walls, seeing the altar, and then heading to the right.

可掛機又可動動腦的遊戲，可惜沒任務
