this game is just incredibly within about 3 hours i knew pretty much the basics and some more complex things in the game. To do many things you must join a city which means you have to build a city house next to a city flag. Then you can get crude oil, find some mines and equip items like boots in your house. This game also doesn't have a specific goal. You could be the richest man, start your own city, or build many flags and conquer a vast amount of land. Its endless. 5/5.
