MCCC is a script mod that enhances gameplay by offering access to functions such as autonomous actions, rates of aging and various settings to simulate story progression and add a bit of drama to your game (something that I often feel is lacking in Sims 4 vs Sims 3)! 💃 MCCC stands for Master Controller Command Center, one of the more popular mods for The Sims 4 that allows detailed control over your game.
