SimSync - The Sims 4 Multiplayer

SimSync – The Sims 4 Multiplayer is a community-created tool/mod that allows players to play The Sims 4 with others in real time, essentially creating a multiplayer experience for a game that is traditionally single-player.

What It Does
  • Enables synchronized gameplay between multiple players in the same save file.
  • Uses a host-client system, where one player acts as the host, and others join their session.

Syncs core gameplay elements like:
  • Sim actions
  • Object states
  • Lot changes
  • Time progression

How It Works

Players must have the same mods, DLC, and game version installed to ensure proper synchronization.

Typically requires setting up through a network connection (either local or via the internet using a direct IP or server).

Once connected, actions from all players reflect in real time, so if one player moves a Sim or builds something, others see it immediately.

Key Features

Co-op Play: Control Sims together, divide responsibilities (e.g., one player handles cooking, another manages kids).

Build Together: Multiple players can build on the same lot simultaneously.

Shared Progress: Everything done in the session saves to the host’s save file.

Chat Feature: Some versions include text chat for easier coordination.

Limitations

Performance-heavy: Requires stable internet and similar PC specs for all players to avoid desync.

Mod Conflicts: Both players need identical mod setups; differences cause issues.

No official support: It’s community-driven, so bugs can happen (e.g., animations not syncing perfectly, occasional lag).

Gameplay Impact
  • Makes storytelling and legacy challenges more engaging by involving friends or family.
  • Great for roleplay, co-op family management, and collaborative builds.
  • Popular among streamers who want shared gameplay experiences.

Compatibility
  • Works with Base Game and most packs, but extra DLC must match for all players.
  • Can be combined with other mods, as long as both players have identical setups.
