The game becoming more complex is not the reason for the empty worlds. That is due to a game engine that is a coin toss. You have winless SIM teams winning the last game of the season against a human team they have no right beating. Heck, I stopped making defensive game plans, and my team does better. And I know I'm not the only one doing this. I hope the new game engine improves the game, or they will see the more leave the game.
