A lot of options. You can build up tiles with different buildings, go to the production of wheat, wood, stone or faith. Or create a balanced option. One option will be good for later abdication and getting gold, the other for hero leveling, the third, for example, for a quick restart, and so on.
You can choose the pantheon (from several options - in a sense, how the pantheon is selected in Civilization 5), and then choose religion and god. Each pantheon has its own effect, and each god has 3 perks, and every perk has its own effect also. In addition, for the gods, you can choose religious servants. There is a lot of combinations.
You can build an academy and hire a hero. Hero fights for tiles. You can choose a hero class. And before each fight, you can choose a weapon, shield and helmet. Again, many options.
The game gradually opens new content, new strategies of the game appear from it.
And since idle...
