How can players make a profit?
There are a few ways. You can move your units around on the map to capture territory in a radius around them. Once a day, a satellite drops from the sky with some Ethereum. If that satellite lands within one of your units' territory then you will win that Ethereum. The amount is based on a portion of the sales. Battling units to prevent them from encroaching on your territory will be important.
In addition, sum up all the territory that you've owned over the course of a day. Depending on what portion you own, we will give a daily dividend to all players on the map. Territory in general becomes more valuable as you move towards the center of the world map since the satellite is more likely to land there and the dividend value increases. Older units will also increase a player's dividend share. I'll be doing a full blog post about this soon!
