SORRY MESSAGE #3, LAST ONE- READ FROM MESSAGE 1:For example, when in nights you become a democracy. What about some kind of event occurs of an election of leaders with different bonuses, that way you don't get bored playing the same leader, or civ in such a long game. Also, there could be area's with in the tech tree, that if you pick a certain tech, it will enhance you with maybe money and power, but, causes unhappiness, and with unhappiness, a new element could develop, an underworld of crime, with black markets. This would bring more challenge to the game play cause you'd have to deal with that as you also build your civ. These are just some elements I wanted to address. I hope you'd like to discuss further, and maybe collaborate.
