1 - Simulation so the players who like the game being in more control than them can watch the programming play out their games.
2 - Non Simulation for those who want user input to be king regardless of “football scores” or unrealistic numbers.
Give the players the option to play the game how they like.
I don’t understand why you would play against a person if you want simulation. I mean if it is 100% sim, you are effectively playing against the game anyway.
