However, once you have MC Command Center installed and enabled, you gain the ability to witness the dynamic lives of all Sims within your game. Without this mod, the lives of non-playable Sims remain static, with no progression in their careers, relationships, or even the ability to start families. One of the key features of MC Command Center is its ability to adjust and manage the story progression of non-playable Sims in your game. This mod is like a Swiss Army knife for your Sims, allowing you to finely tune and control various aspects of their lives. MC Command Center, developed by Deaderpool, is a popular mod for The Sims 4 that provides players with a range of powerful customization and management options.
