MCCC, or MC Command Center, is a mod most people use to create automated story-progression with NPCs or previously played households.
Those playing on laptops, I recommend keeping groups of Sims to the game's default. If you are concerned about performance for larger groups of Sims, I've included my computer build at the bottom of this post for reference. A quick search for 'mccc sims 4 guide' brings up a few different video options that might be a better fit for you. If you are more of a visual learner, there are some videos out there that can help as well! I'm more of a reader myself. Now that I've tweaked and adjusted the mod in my game for about six months, I feel confident providing others who were like me a more detailed guide of the mod. All I really wanted was a list of settings to attain story progression in my game that also detailed exactly what each setting did. This stemmed from me originally being completely overwhelmed by the mod when I first got it. I had the idea of doing a detailed breakdown of what the mod MCCC is by Deaderpool, as well as providing my personal in-game settings detailing exactly what each of them does.
EDIT: I have since updated this post with more categories and settings! Anything new is marked with '*NEW*'.
