Is AFK gaming more profitable?

The amount of gold you receive when the game is closed is higher than the amount you receive when the game is open, assuming you are not actively playing the game. I ran a few tests with my game and the results are as follows:

30 minutes game open               => 10,883q gold
30 minutes game closed             => 12,246q gold
30 minutes game open, using skills => 18,361q gold

I didn't do 30 minutes of clicking and using skills because that's boring.

So, if you aren't actively playing the game, close the browser tab. You'll gain more gold.
