Hehe, I was thinking the same thing...Travian is too much too often, and GLB is too little not often enough. I still like this since I know that I can forget about it for a time and still not miss out on anything, and I really think that over time you can get to where you are as busy as you want to be.
You have minor adjustments you can make, adjust training to make sure you are reseted, tweak your tactics based on who you play next....and later you have contracts to remember and you can talk to owners about setting yourself to be on a good fit for a team...etc.
As long as you are only using 1 account, you can have as many players as you want, but you can also use those flex points to boost your players level 3 times a season as well, which gives them a level up.
